It is aimed to investigate the geometric parameters of the crankshaft affecting the mass flow rate of the lubricant released from the outlet of the crankshaft. The change of the mass flow rate from the outlet of the crankshaft associated with helix-screw indicates that with reducing the screw pitch, the mass flow rate decreases. An important finding is that increasing the depth of the helical channel plays a more significant role than increasing the width of the helical channel. The mass flow rate increases when the distance between the suction hole of the crankshaft and the oil sump bottom increases. The wall thickness of the crankshaft does not significantly affect the mass flow rate whereas it plays a crucial role in formation of the vortices around the crankshaft.KeywordsHermetic reciprocating compressorLubricationHelical channelComputational Fluid Dynamics (CFD)Volume of Fluid (VoF)Mots clésCompresseur à piston hermétiqueLubrificationCanal hélico?dalDynamique des fluides mécanique (CFD)Volume du frigorigène (VoF)Check if you have access through your login credentials or your institution.ororRecommended articlesCiting articles (0)CFD-POST后处理_图文_百度文库

Numerical Simulation of Pipeline Leak Noise Analysis
JI Xia,WU Ya-feng,YANG Hao(The College of Power and Energy of The Northwestern Polytechnical University,Xi'an Shanxi 710072,China)
At present,the pipe leak noise is mainly obtained by experiment,the way is restricted by the model size,measurement accuracy and other constraints,In this paper,based on generalized Lighthill theory,we simulate the flow field of the transmission pipe by commercial software fluent,set the boundary conditions according to the actual situation.Through large-eddy simulation and FFT of the leakage point pressure,sound pressure frequency spectrum is obtained.This work have some reference value for the analysis and monitoring of actual piprline leak sound field.
