Flow through an eccentric longitudinal clearance ring

摘要

In this work there are presented flow calculation models through the longitudinal eccentric throttle clearance ring. There are shown some calculations for laminar and turbulent flow. Turbulent flow is described as self-similar and with application of model k - e, the description is illustrated with calculative example. The measurement results of pressure fields measured in the longitudinal eccentric clearance are presented. The calculation results obtained with different methods are compared with one another.
