Résumé

The aim of this paper is to present the numerical resolution of suction muffler configurations (by means of a tridimensional, unstructured, parallel and object oriented CFD&HT TermoFluids code (Lehmkuhl, et al. 2007) specially adapted to low Mach models (Lopez et al. 2012), coupled with the numerical resolution of the whole compressor domain (by means of a modular, unstructured and object oriented NEST-compressors tool (Damle et al. 2011) to simulate the thermal and fluid dynamic behavior of hermetic reciprocating compressors). The numerical results aim to evaluate the influence of the suction muffler geometry on the mass flow rate and compressor efficiency performance, while considering the whole compressor working conditions in a coupling manner. In that sense, the CFD&HT resolution of the muffler is obtained with boundary conditions obtained from the numerical simulation of the rest of the hermetic reciprocating compressor. The use of Large Eddy Simulation (LES) models for the turbulent suction muffler analysis; the adaptation of Low Mach formulation avoiding the full incompressible numerical problem, and the coupling of a numerical simulation model of the whole compressor as boundary conditions, are the important updated numerical aspects presented in this paper.
