Résumé

A mathematical model was developed to study flow characteristics in non-adiabatic capillary tubes. The theoretical model is based on conservation of mass, energy and momentum of fluids in the capillary tube and suction line. The mathematical model was categorized into three different cases, depending on the position of the heat exchange process. A set of differential equations was solved by the explicit method of finite-difference. The model was validated by comparing with the experimental data obtained from previous studies. The results obtained show reasonable agreement with the experimental data. The present non-adiabatic capillary tube model can be used to integrate with system models working with alternative refrigerants for design and optimization.
