A two-fluid model for refrigerant flow through adiabatic capillary tubes
(Abcm Brazilian Soc Mechanical Sciences & Engineering, 2014-01-01)
This work presents a numerical model to simulate refrigerant flow through capillary tubes, commonly used as expansion devices in refrigeration systems. The flow is divided in a single-phase region, where the refrigerant ...
Evaluation of an Immersed Boundary Method for solving the fluid structure interaction problem in refrigeration compressor valves
(2014-01-01)
In refrigeration compressors, the suction and discharge valves are responsible for the retention of the refrigerant from the suction chamber to the cylinder and passage from the cylinder to the discharge chamber. As the ...
