A ROBUST MODELING APPROACH FOR SIMULATING REFRIGERANT FLOW THROUGH CAPILLARY TUBES

摘要：

A novel computational model for simulating refrigerant flow through capillary tubes is proposed and validated using a dataset composed of 1005 experimental data points, including adiabatic and non-adiabatic flows of refrigerants HFC-134a and HC-600a. The modeling approach is based on the mass, energy and momentum conservation principles written according to their one-dimensional differential formulation. Some simplifications were added to the model in order to improve its numerical stability. It was found that the model predicts 87％ of the measured refrigerant mass flow rate for adiabatic and 76％ for non-adiabatic flow within an error band of ±10％.
