A Review on Predicting the Refrigerant Flow Characteristics

A comprehensive review of the literature on the flow of various refrigerants through the capillary tubes of different geometries viz. straight and coiled and flow configurations viz. adiabatic and diabatic, has been discussed in this paper. This paper give a brief study about throttling expansion of refrigerant, capillary tube, refrigerant property and mathematical correlation for the flow through the capillary tubes of different geometries operating under adiabatic and diabatic flow conditions
