Abstract

In order to obtain the influence of different working fluids on the liquid-vapor separation in the liquid separation header

a numerical simulation was carried out with the same mass flow rate and vapor quality as the comparison benchmark. Based on the VOF(Volume of Fluid) multiphase model

the liquid-vapor separation among six working fluids was simulated. The property variables were density

viscosity and surface tension. The result demonstrated that the liquid-vapor separation state will change under the influence of liquid vapor density ration. In addition

it was found that R134a had the best performance in liquid-vapor separation

while R1234ze(E) could replace R134a well. The optimization direction of other working fluid to improve the performance of liquid-vapor separation was also given.
