Traitement du transfert de chaleur dans les petits compresseurs à piston.
Treatment on heat transfer in small piston compressors.
Auteurs : BIELMEIER O., MUELLNER T.
Résumé
This paper presents an investigation about heat transfer in small, fast running piston compressors. An introductory chapter outlines the motivation of this investigation and gives some insight into the necessity to deal with heat transfer. Starting with some basics of heat transfer in general focus is laid on the heat transfer from the compression chamber into adjacent structures. The basic modelling of the piston and valve motion is described as well as the dynamic discretization of the fluid volume. Time-dependent heat fluxes and heat transfer coefficients are calculated for all involved physical interfaces. It is shown how the variation of pure geometrical terms influences the thermal behaviour of the whole system. Experimental data were gathered to evaluate the degree of accuracy of the numerical model. A short outlook of how these results could help to optimize the valve system from the thermal point of view concludes the paper.
