Modeling the HFC134a flow capillary tubes using a two-fluid model.

Author(s) : SEIXLACK A. L., PRATA A. T., MELO C.

Summary

The paper presents a numerical model to simulate the R134A flow through capillary tubes. The capillary tube is considered straight and horizontal; the flow is taken as one-dimensional, steady and adiabatic. A two-fluid model, involving five conservation equations and considering the hydrodynamic and thermal nonequilibrium between the liquid and vapour phases, is applied to the two-phase flow region. Computed pressure profiles and mass flow rates obtained from the model are compared with experimental data. It is shown that the present model yields better results than the commonly employed homogeneous model.
