The flow is divided in a liquid single-phase region and in a two-phase region, in which the homogeneous model is used to simulate the flow. hypoglycemia and perimenopauseWebcompressor, in fact the radial clearance is filled with a mixture composed by the oil and the refrigerant, because these fluid are mutually miscible. Most previous researchers have modeled this leakage as an isothermal single phase flow of pure refrigerant gas or pure lubricant oil. Pandeya and Soedel (1978), Yanagisawa and Shimizu hypoglycemia and nauseaWebbimetal bearings, the wall tolerance is .0003” per shell or .0006” in total. Adding these up, we get .0010” for the housing + .0010” for the shaft + .0006” for the bearings = .0026” total clearance variation possible due to mating part manufacturing tolerances.
