A Mean-Line Model to Predict the Design Performance of Radial Inflow Turbines in Organic Rankine Cycles
UNIVERSITÀ DEGLI STUDI DI PADOVA DIPARTIMENTO DI INGEGNERIA INDUSTRIALE CORSO DI LAUREA MAGISTRALE IN INGEGNERIA ENERGETICA TECHNISCHE UNIVERSITÄT BERLIN INSTITUT FÜR ENERGIETECHNIK Tesi di Laurea Magistrale in Ingegneria Energetica A MEAN-LINE MODEL TO PREDICT THE DESIGN PERFORMANCE OF RADIAL INFLOW TURBINES IN ORGANIC RANKINE CYCLES Relatori: Prof. Andrea Lazzaretto Prof.ssa Tatjana Morozyuk (Technische Universität Berlin) Correlatore: Ing. Giovanni Manente Laureando: ANDREA PALTRINIERI ANNO ACCADEMICO 2013/2014 ii Abstract This Master Thesis contributes to the knowledge and the optimization of radial inflow turbine for the Organic Rankine Cycles application. A large amount of literature sources is analysed to understand in the better way the context in which this work is located. First of all, the ORC technology is studied, taking care of all the scientific aspects that characterize it: applications, cycle configurations and selection of the optimal working fluids. After that, the focus is pointed on the expanders, as they are the most important components of this kind of power production plants. Nevertheless. Their behaviour is not always wisely considered in an organic vision of the cycle. In fact, it has been noticed that mostly literature concerning the optimization of ORC considers the performances of the expander as a constant, omitting in this way an essential part of the optimisation process. Starting from these observations, in this Master Thesis radial inflow turbines are carefully analysed, performing a theoretical investigation of the achievable performance. Starting from a critical study of publications concerning the design of radial expanders, a theoretical model is proposed. Then, a design procedure of the geometrical and thermo dynamical characteristics of radial inflow turbine operating whit fluid R-245fa is implemented in a Matlab code. -

Cambaa, Manuel Conterob, Pedro Companyc aUniversity of Houston. Houston, TX. [email protected] bUniversitat Politècnica de València. Valencia, Spain. [email protected] cUniversitat Jaume I, Castellón, Spain. [email protected] Abstract CAD model quality in parametric design scenarios largely determines the level of flexibility and adaptability of a 3D model (how easy it is to alter the geometry) as well as its reusability (the ability to use existing geometry in other contexts and applications). In the context of mechanical CAD systems, the nature of the feature-based parametric modeling paradigm, which is based on parent-child interdependencies between features, allows a wide selection of approaches for creating a specific model. Despite the virtually unlimited range of possible strategies for modeling a part, only a small number of them can guarantee an appropriate internal structure which results in a truly reusable CAD model. In this paper, we present an analysis of formal CAD modeling strategies and best practices for history-based parametric design: Delphi’s horizontal modeling, explicit reference modeling, and resilient modeling. Aspects considered in our study include the rationale to avoid the creation of unnecessary feature interdependencies, the sequence and selection criteria for those features, and the effects of parent/child relations on model alteration. We provide a comparative evaluation of these strategies in the form of a series of experiments using three industrial CAD models with different levels of complexity. -
Parametric Design Thinking About Digital and Material Surface Patterns
INTERNATIONAL CONFERENCE ON ENGINEERING AND PRODUCT DESIGN EDUCATION 6 & 7 SEPTEMBER 2018, DYSON SCHOOL OF DESIGN ENGINEERING, IMPERIAL COLLEGE, LONDON, UNITED KINGDOM PARAMETRIC DESIGN THINKING ABOUT DIGITAL AND MATERIAL SURFACE PATTERNS Wenche LYCHE, Arild BERG and Kristin ANDREASSEN OsloMet – Oslo Metropolitan University ABSTRACT There is a growing need in contemporary society to understand new and emerging relationships between technology and creativity. In practice-oriented areas of education such as design, many instructors have come to understand the importance of different learning styles and how students benefit when presentation of new material is varied to reach all students. The concept of parametric design thinking enabled by advanced computational processes has recently been identified as a relevant approach to design education. The present research further explores parametric design thinking through two case studies of design workshops in an educational context and how this approach can promote diversity. The first case (Robotised Clay Workshop) documents material exploration and creative and aesthetic possibilities in digitalised clay processes. The second case (Surface Patterns in Textiles: From Tradition to Digitalisation and Back) explores digitalised processes in hybrid textile design. The two case studies contribute to the exploration of parametric design thinking as an educational approach and discuss digitalisation and the relations of body, hand and mind in terms of the Vygotskyan ‘zone of proximal development’. This content was synthesised for a workshop on surface patterns for third-year bachelor design students. The paper identifies some potentials and pitfalls of this pedagogical approach and concludes that students’ awareness of conformity and diversity in the design process can be used as a starting point to explore digital surface patterns, offering students a new way of learning about function, aesthetics and product semantics through parametric design thinking. -

Design of Parametric Software Tools: Optimizing Future Health Care Performance by Integrating Evidence-Based Knowledge in Architectural Design and Building Processes
Lighting in Engineering, Architecture and the Environment 37 Design of parametric software tools: optimizing future health care performance by integrating evidence-based knowledge in architectural design and building processes J. B. Sabra & M. Mullins Department of Architecture, Design and Media Technology, Aalborg University, Denmark Abstract The studies investigate the field of evidence-based design used in architectural design practice and propose a method using 2D/3D CAD applications to: 1) enhance integration of evidence-based design knowledge in architectural design phases with a focus on lighting and interior design and 2) assess fulfilment of evidence-based design criterion regarding light distribution and location in relation to patient safety in architectural health care design proposals. The study uses 2D/3D CAD modelling software Rhinoceros 3D with plug-in Grasshopper to create parametric tool prototypes to exemplify the operations and functions of the design method. To evaluate the prototype potentials, surveys with architectural and healthcare design companies are conducted. Evaluation is done by the administration of questionnaires being part of the development of the tools. The results show that architects, designers and healthcare design advisors recon the tool prototypes as a meaningful and valuable approach for 1) integrating and using evidence-based information; and 2) optimizing design processes and health care facility performances. Further study focuses on parametric information relations in Building Information -
Design Methods for Democratising Mobile Game Design
Design Methods for Democratising Mobile Game Design Mark J. Nelson Abstract Swen E. Gaudl Playing mobile games is popular among a large and Simon Colton diverse set of players, contrasting sharply with the lim- Rob Saunders ited set of companies and people who design them. We Edward J. Powley would like to democratise mobile game design by ena- Peter Ivey bling players to design games on the same devices they Blanca Pérez Ferrer play them on, without needing to program. Our concept Michael Cook of fluidic games aims to realise this vision by drawing on three design methodologies. The interaction style of The MetaMakers Institute fluidic games is that of casual creators; their end-user Falmouth University design philosophy is adapted from metadesign; and Cornwall, UK their technical implementation is based on parametric metamakersinstitute.com design. In this short article, we discuss how we’ve adapted these three methods to mobile game design, and some open questions that remain in order to em- power end user game design on mobile phones in a way that rises beyond the level of typical user- generated content. Author Keywords Mobile games; casual creators; metadesign; parametric design; end-user creativity; mixed-initiative interfaces. ACM Classification Keywords H.5.m. Information interfaces and presentation: Miscel- laneous Introduction Fluidic Games Our starting point is the observation that mobile games To support on-device casual design, we are developing have attracted a large and diverse set of players, but a what we call fluidic games [5-7]. These blur the line smaller and less diverse set of designers. -

GUI-Based Chinese Font Editing System Using Font Parameterization Technique
Typography and Diversity http://www.typoday.in GUI-based Chinese Font Editing System Using Font Parameterization Technique Minju Son, School of Computer Science and Engineering, Soongsil University, [email protected] Gyeongjae Gwon, School of Computer Science and Engineering, Soongsil University, [email protected] Jaeyeong Choi, School of Computer Science and Engineering, Soongsil University, [email protected] Geunho Jeong, Gensol Soft, Seoul, Korea, [email protected] Abstract: When creating Roman fonts, about 256 characters should be designed. Whereas creating Chinese fonts, around 8,000 widely used characters should be designed from the total 80,000 to 100,000 characters. In order to solve these problems, many studies on programmable fonts have been performed since 1980s. METAFONT is a font designing system for improving the quality of TeX typesetting in TeX document, and it represents programmable fonts. However, as METAFONT is a programming language, it is very difficult for general font designers to design fonts directly by using it. In order to solve this problem, we propose a GUI-based Chinese font editing system by font parameterization technique, which can easily edit fonts in web browser. Key words: Font Editor, Programmable Font, Font Parameterization, METAFONT. 1. Introduction Recently, the development of portable devices has increased the number of places where fonts are essential, such as e-books, websites, mobile games, books, newspapers, etc. When creating Roman fonts, about 256 characters should be designed. Whereas creating Chinese fonts, around 8,000 widely used characters should be designed from the total 80,000 to 100,000 characters. When generating fonts, characters are generally described as ‘outline’.
