COMPRESSOR MUFFLER DESIGN CONSIDERING FLUID-STRUCTURE INTERACTION

This paper investigates the importance of considering fluid-structure interaction (FSI) while designing new suction/discharge mufflers made of polymeric material. This necessity arose from experimental results deviating from simulations of such components, considering only standard transmission loss simulations with rigid walls. For that reason, we simulated new FE models with ANSYS software and ACT add-on, with and without FSI, to evaluate the relevance of their differences. Furthermore, the results from new FE models were correlated with experiments to assess its significance. Finally, a heuristic optimization process was carried, and different designs of mufflers were simulated, prototyped and tested under working conditions. The results, originated from the optimization, are discussed.
