Jagadale 1, Prof V. R. Gambhire2 P.G. Student, Department of Mechanical Engineering, Tatyasaheb Kore Institute of Engineering and Technology, Warananagar, Maharashtra, India1 Associate Professor, Department of Mechanical Engineering, Tatyasaheb Kore Institute of Engineering and Technology, Warananagar, Maharashtra, India 2 ABSTRACT: This paper discusses concept of Quasi turbine (QT) engines and its application in industrial systems and new technologies which are improving their performance. The primary advantages of air engine use come from applications where current technologies are either not appropriate or cannot be scaled down in size, rather there are not such type of systems developed yet. One of the most important things is waste energy recovery in industrial field. As the natural resources are going to exhaust, energy recovery has great importance. This paper represents a quasi turbine rotary air engine having low rpm and works on low pressure and recovers waste energy may be in the form of any gas or steam. The quasi turbine machine is a pressure driven, continuous torque and having symmetrically deformable rotor. This report also focuses on its applications in industrial systems, its multi fuel mode. In this paper different alternative methods discussed to recover waste energy. The quasi turbine rotary air engine is designed and developed through this project work. KEYWORDS: Quasi turbine (QT), Positive displacement rotor, piston less Rotary Machine. I. INTRODUCTION A heat engine is required to convert the recovered heat energy into mechanical energy. -
Small Scale ORC Plant Modeling with the Amesim Simulation Tool: Analysis of Working Fluid and Thermodynamic Cycle Parameters Influence
Available online at www.sciencedirect.com ScienceDirect Energy Procedia 81 ( 2015 ) 440 – 449 69th Conference of the Italian Thermal Engineering Association, ATI 2014 Small scale ORC plant modeling with the AMESim simulation tool: analysis of working fluid and thermodynamic cycle parameters influence. M. Antonelli*, A. Baccioli, M. Francesconi, P. Psaroudakis, L. Martorano Università di Pisa, D.E.S.Te.C., Largo Lucio Lazzarino, Pisa 56122, Italy Abstract ORC plant transient modeling is an actual issue for the correct assessment of the size of the various components of the system especially when unpredictable fluctuations of the inlet thermal flux are to be considered. This work shows the modeling procedure of a small scale (10-50 kW) Waste Heat Recovery ORC plant which uses an innovative expansion device derived from a Wankel engine. The numerical model here presented was developed with the simulation tools AMESim and simulates the transient behavior of such a small scale system in all its main components: preheater, evaporator, expansion device and condenser. The aims of this work were to evaluate the suitability of the Wankel-derived mechanism to ORC systems and to establish its optimal working conditions for the employment in a low-grade heat recovery system. The application of several working fluids as well as of various operating conditions are presented in this paper. The analysis of the transient response of the plant is also presented with a particular attention to start up operations. © 20152015 Published The Authors. by Elsevier Published Ltd.

Kashibai Navale College of Engineering, Pune;[email protected], 2Student,Department of Mechanical Engineering, Smt. Kashibai Navale College of Engineering, Pune; [email protected] ABSTRACT This paper reviews the concept of a Quasiturbine (also known as Qurbine) Engine and its potential as a replacement for the standard Piston Engine. The Quasiturbine Rotary Air Engine is a low rpm engine, working on low pressure. For this purpose, a binary system of Quasiturbines is also used. It also discusses the multi-fuel capability of Quasiturbine and how it can be used in vehicle propulsion systems. This piston-less rotary machine is intended to be used where the existing technologies are centuries old and have numerous insurmountable problems. It has been consistently observed that this engine provides a better efficiency, much smaller ratio of unit displacement to engine volume, extremely high power per cycle and reduced emissions. Key words: Quasiturbine, standard piston engine, piston-less rotary engine, deformable rotor. I. INTRODUCTION A. Need and Invention Dr. Gilles Saint-Hilaire, a thermonuclear physicist, after thoroughly studying the limitations of conventional engines, designed the Quasiturbine Engine. The Quasiturbine is a continuous Torque, symmetrically deformable spinning wheel. The Saint-Hilaire family used a modern computer based approach to map the conventional engine characteristics with optimum physical-chemical graphs. -

Scope of Quasi Turbine:A Review Analysis Pranjal Yadav, Amit Tiwari, Anuj Gupta, Sushant Verma, Sandeep Kumar Singh Department of Mechanical Engineering, G. L. Bajaj Institute of Technology and Management, India ABSTRACT Piston engine is the main power supply of all kinds of mobile equipment’s, and its power density directly affects the performance of mobile equipment. Compared with electric motor and gas turbine power, the piston engine has a smaller volume, simpler structure, and larger power density etc., therefore it becomes the most common source of power. Present paper provides the review analysis for the Quasi Turbine including its comparison, design analysis and future scope of work. Keywords – Quasiturbine, Rotory Engine I INTRODUCTION Rotary piston engines have the basic characteristics different from traditional piston engine which is that under pressure torque, its piston rotates around the output shaft instead of reciprocating motion in the cylinder. The working process of the cylinders, although in some points it has its own characteristics, is almost simile as the original reciprocating work cycle in nature. On the one hand, it is freed of the reciprocating inertia force for the privilege of high speed, and on the other hand, to a certain extent, it keeps the economy of traditional piston engine. So, its emergence is the major technological changes on the structure of internal combustion engine [1]. Over the years, like this rotational structure, many kinds of solutions were put forward. By now in addition to Wankel rotary engine, others did not become a formal product 1.1. About Quasi Turbine The QT (QT) is the most compact and efficient tool currently available for compression and expansion of most working fluids. -

Academic Editors: Paul Stewart and Chris Bingham Received: 19 March 2015 / Accepted: 17 July 2015 / Published: 4 August 2015 Abstract: The purpose of this paper is to investigate combustion characteristics for rotary engine via numerical studies. A 3D numerical model was developed to study the influence of several operative parameters on combustion characteristics. A novel rotary engine called, “Leaf Spring Rotary Engine”, was used to illustrate the structure and principle of the engine. The aims are to (1) improve the understanding of combustion process, and (2) quantify the influence of rotational speed, excess air ratio, initial pressure and temperature on combustion characteristics. The chamber space changed with crankshaft rotation. Due to the complexity of chamber volume, an equivalent modeling method was presented to simulate the chamber space variation. The numerical simulations were performed by solving the incompressible, multiphase Unsteady Reynolds-Averaged Navier–Stokes Equations via the commercial code FLUENT using a transport equation-based combustion model; a realizable turbulence model and finite-rate/eddy-dissipation model were used to account for the effect of local factors on the combustion characteristics. -
