This study presents improved refrigerant characteristics flow predictions using homogenous flow
model in adiabatic capillary tube, used in small vapor compression refrigeration system. The model is based
on fundamental equations of mass, momentum and energy. In order to improve the flow predictions, the
inception of vaporization in the capillary tube is determined by evaluating initial vapor quality using enthalpy
equation of refrigerant at saturation point and the inlet entrance effect of the capillary tube is also accounted
for. Comparing this model with experimental data from open literature showed a reasonable agreement. Further
comparison of this new model with earlier model of Bansal showed that the present model could be use to
improve the performance predictions of refrigerant flow in adiabatic capillary tube.
