  • Optimization Design by Coupling Computational Fluid Dynamics and Genetic Algorithm 125
    DOI: 10.5772/intechopen.72316 Provisional chapter Chapter 5 Optimization Design by Coupling Computational Fluid OptimizationDynamics and Design Genetic by Algorithm Coupling Computational Fluid Dynamics and Genetic Algorithm Jong-Taek Oh and Nguyen Ba Chien Jong-TaekAdditional information Oh and is availableNguyen at Bathe endChien of the chapter Additional information is available at the end of the chapter http://dx.doi.org/10.5772/intechopen.72316 Abstract Nowadays, optimal design of equipment is one of the most practical issues in modem industry. Due to the requirements of deploying time, reliability, and design cost, bet- ter approaches than the conventional ones like experimental procedures are required. Moreover, the rapid development of computing power in recent decades opens a chance for researchers to employ calculation tools in complex configurations. In this chapter, we demonstrate a kind of modern optimization method by coupling computational fluid dynamics (CFD) and genetic algorithms (GAs). The brief introduction of GAs and CFD package OpenFOAM will be performed. The advantage of this approach as well as the difficulty that we must tackle will be analyzed. In addition, this chapter performs a study case in which an automated procedure to optimize the flow distribution in a manifold is established. The design point is accomplished by balancing the liquid-phase flow rate at each outlet, and the controlled parameter is a dimension of baffle between each chan- nel. Using this methodology, we finally find a set of results improving the distribution of flow. Keywords: computational fluid dynamics, VOF, optimization, OpenFOAM, genetic algorithm, open sourced 1. Introduction Computational fluid dynamics (CFD)-based optimization approach has been growing rap- idly in the past decades.

  • Development of a Coupling Approach for Multi-Physics Analyses of Fusion Reactors
    Development of a coupling approach for multi-physics analyses of fusion reactors Zur Erlangung des akademischen Grades eines Doktors der Ingenieurwissenschaften (Dr.-Ing.) bei der Fakultat¨ fur¨ Maschinenbau des Karlsruher Instituts fur¨ Technologie (KIT) genehmigte DISSERTATION von Yuefeng Qiu Datum der mundlichen¨ Prufung:¨ 12. 05. 2016 Referent: Prof. Dr. Stieglitz Korreferent: Prof. Dr. Moslang¨ This document is licensed under the Creative Commons Attribution – Share Alike 3.0 DE License (CC BY-SA 3.0 DE): http://creativecommons.org/licenses/by-sa/3.0/de/ Abstract Fusion reactors are complex systems which are built of many complex components and sub-systems with irregular geometries. Their design involves many interdependent multi- physics problems which require coupled neutronic, thermal hydraulic (TH) and structural mechanical (SM) analyses. In this work, an integrated system has been developed to achieve coupled multi-physics analyses of complex fusion reactor systems. An advanced Monte Carlo (MC) modeling approach has been first developed for converting complex models to MC models with hybrid constructive solid and unstructured mesh geometries. A Tessellation-Tetrahedralization approach has been proposed for generating accurate and efficient unstructured meshes for describing MC models. For coupled multi-physics analyses, a high-fidelity coupling approach has been developed for the physical conservative data mapping from MC meshes to TH and SM meshes. Interfaces have been implemented for the MC codes MCNP5/6, TRIPOLI-4 and Geant4, the CFD codes CFX and Fluent, and the FE analysis platform ANSYS Workbench. Furthermore, these approaches have been implemented and integrated into the SALOME simulation platform. Therefore, a coupling system has been developed, which covers the entire analysis cycle of CAD design, neutronic, TH and SM analyses.

When coding the case file, it is possible to create the geometrical elements using built-in functions of GPUSPH (only for particle-type boundary conditions at the moment) or to read particle files generated by the Particle Preprocessor module of SALOME. Creating a case by hand corresponds to the creation of a new cusource file, with the associated header (e.g. MyCase.cu and MyCase.h), placing them under src/problems/user. This folder does not exist by default in GPUSPH, but it is recognised as a place to be scanned for case sources.

  • Development of a Support Tool to Predict Manufacturability of Deep- Drawing Parts
    INTERNATIONAL DESIGN CONFERENCE - DESIGN 2016 Dubrovnik - Croatia, May 16 - 19, 2016. DEVELOPMENT OF A SUPPORT TOOL TO PREDICT MANUFACTURABILITY OF DEEP- DRAWING PARTS D. Goller, S. Schreyer, B. Alber-Laukant, F. Rieg and W. Volk Keywords: process analysis, deep drawing, geometric modeling kernel, feasibility analysis 1. Introduction There are several different approaches to develop new products. A popular example is the product development process (PDP) by Pahl/Beitz [Feldhusen and Grote 2013]. The development engineer always benefits from detailed knowledge from later stages of the PDP, like process knowledge. Most likely this information is not available at these early stages, so it could be transferred from similar cases, which already have completed this stage, or the information can be generated by fast but preferably accurate estimations. The main goal of the collaborative research centre FORPRO², supported by the Bavarian research foundation (Bayerische Forschungsstiftung - BFS), is the optimization of simulation based development by knowledge transfer. One aspect of before mentioned optimization is the development of a software tool to predict the manufacturability of deep drawing parts. This can be achieved by process simulation by means of finite element analysis, but getting reliable output is usually extremely time-consuming and requires detailed process knowledge. Especially in early stages of the development process, a fast prediction on basis of non-detailed data is more expedient. There is already an approach to create a fast assumption of the manufacturability by using One-Step- solvers, which are already available in commercial solutions as for intance Autoform-OneStepforCatia [AutoForm 2015] and Altair HyperForm [Altair Engineering Inc.

CEA and EDF are using SALOME to perform a wide range of simulations, which are typically related to industrial equipment in power plants (nuclear power plants, wind turbines, dams…). Some primary concerns are the design of new-generation reactor types, nuclear fuel management and transport, material ageing for the life-cycle management of equipment, and the reliability and safety of the nuclear facilities.

  • Simulation Modelling for Computer Aided Design of Secondary Aerodynamic Wing Surfaces Aleksandr A
    Advances in Systems Science and Application (2015) Vol.15 No.4 338-350 Simulation Modelling for Computer Aided Design of Secondary Aerodynamic Wing Surfaces Aleksandr A. Gorbunov, Aleksej D. Pripadchev, Irina S. Bykova and Valerij V. Elagin Federal State Educational Government-financed Institution of Higher Professional Education, Orenburg State University, Orenburg region, Russia Abstract The simulation modelling technique of secondary aerodynamic wing surface of the long-haul aircraft using a high-precision mathematical simulation in the aerody- namics and hydrodynamics computer programme has been formulated in the present article. The method proposed is based on the modern methods in the field of computer-aided design of aircraft using CATIA three-dimensional sim- ulation and simulation modelling in SALOME environment. The use of high- precision mathematical simulation in computer-aided design of secondary aero- dynamic wing surfaces allows us to determine the aerodynamic characteristics of the secondary aerodynamic surface of the model developed and to verify the previous results of the project definition. Keywords Secondary aerodynamic surfaces; High-precision computer mathemat- ical simulation; Simulation model; A long-haul aircraft; Synthesis; Design au- tomation; Project procedures; Three-dimensional modelling 1 Introduction Building the new long-haul aircraft (A/C) with improved performance character- istics and enhancing the currently used aircraft is effected in various ways. One of them is improving its aerodynamics depending largely on the A/C look. In our view, the most rational way to improve the aerodynamic characteristics of the A/C is to install the secondary aerodynamic surfaces (SAS) at the wingtip. The use of SAS reduces the induced drag of the aircraft, enhances the effective wing aspect-ratio and ascensional power at the wingtip, improves A/C longitu- dinal/transverse stability, reduces specific fuel consumption, cuts takeoff run and landing roll of the aircraft.
