NUMERICAL MODELLING OF THERMODYNAMIC NON-EQUILIBRIUM FLOW OF REFRIGERANT THROUGH CAPILLARY TUBES.

Author(s) : LI R. Y., LIN S., CHEN Z. H.

Summary

A MODEL FOR A STEADY-STATE, TWO-PHASE FLOW IN CAPILLARY TUBES, CONSIDERING THE THERMODYNAMIC NON-EQUILIBRIUM PHENOMENON DURING VAPORIZATIONAND THE RELATIVE VELOCITY BETWEEN THE LIQUID AND VAPOUR, HAS BEEN DEVELOPED. THE 5 DIFFERENTIAL EQUATIONS BASED ON THE DRIFT FLUX MODEL OF TWO-PHASE FLOWS ARE SOLVED BY USING THE RUNGE-KUTTA METHOD SIMULTANEOUSLY. A COMPARISON IN GOOD AGREEMENT WITH EXPERIMENTAL DATA OBTAINED FROM TWO-PHASE FLOW OF R12 FLOWING THROUGH CAPILLARY TUBES SHOWS THAT THE MODEL IS PRACTICAL.
