Investigation Study of the Inlet to Body Diameter Ratio of a Vertical Flash Tank Separator using Computational Fluid Dynamic (CFD)

Abstract
The vertical flash tank separator improves the heat transfer coefficient in the evaporator of the mechanical refrigeration system. However, enhancing and improving the performance of the vertical flash tank separator need further investigation. In order to provide an optimum design and performance of a vertical flash tank separator, this paper provides an investigation study to present the effect of the inlet to body diameter ratio (d/D) of the vertical flash tank separator on the separator’s performance. Computational Fluid Dynamic (CFD) was used to design the optimum ratio configuration. The results revealed that the d/D has significant effect on the liquid separation efficiency. The CFD simulations give a good agreement with the experiments, all the simulations underestimated the liquid separation efficiency by approximately 0.02 over the range of conditions tested.
