Titre :	Two-dimensional numerical simulation of a scroll expander for ORC applications
Type de document :	Travail de fin d'études
Auteurs :	Louis Dubail, Auteur ; Giovanna Cavazzini, ; Patrick Hovine
Editeur :	ECAM
Année de publication :	2018
Note générale :	Universita degli Studi di Padova
Langues :	Anglais (eng)
Index. décimale :	TFE - Electromécanique
Résumé :	Over the past few decades, the study of scroll expanders has brought a lot of interest in research, as they are able to recover and transform low-grade temperature energy into mechanical energy and finally into electrical energy. As they are difficult to modelize and simulate in CFD (Computational Fluid Dynamis) softwares, several different approaches exist to try and resolve the problem. The literature describes different geometries and different techniques in order to simulate the system in the best and most realistic way. Therefore, this thesis will try to bring some elements of answer in order to carry out a two-dimensional simulation of a scroll expander, using dynamic meshing technique in Ansys-CFX software. In order to do that, a simple geometry will be computed in Matlab and then exported to a text file, to be able to create a mesh in Ansys. The thesis is expected to supply a basis for further studies on more accurate 2D or 3D models of scroll expanders.
