Foam flow of oil-refrigerant R12 mixture in a small diameter tube
(Associação Brasileira de Engenharia e Ciências Mecânicas - ABCM, 2006-12)
This paper presents an experimental investigation of the mineral oil ISO VG10-refrigerant R12 mixture flow with foam formation in a straight horizontal 3.22 mm ID, 6.0 m long tube. An experimental apparatus was designed ...
Transient flow of the oil-refrigerant mixture through the radial clearance in rolling piston compressors
(1999-12-01)
Unsteady flow of oil and refrigerant gas through radial clearance in rolling piston compressors has been modeled as a heterogeneous mixture, where the properties are determined from the species conservation transport ...
