This chapter presents a numerical approach for simulating the distillation process with the CFD software FLUENT. The model solves the Navier-Stokes equations. It also incorporates the evaporation of liquid in the boiling chamber and the condensation of vapor in the condenser. The findings suggest that CFD is a valuable tool for simulating and forecasting the flow dynamics in a water distiller. Additionally, the study explores the impact of adjusting the empirical coefficient in the Lee model. It has been shown that the flowrate of the pure water in the storage bottle increases with the increase of the value of this coefficient. We found that a coefficient value of 1.4 yields a flow rate that is closest to the manufacturer’s specified rate of 1 L/h.

摘要

This chapter presents a numerical approach for simulating the distillation process with the CFD software FLUENT. The model solves the Navier-Stokes equations. It also incorporates the evaporation of liquid in the boiling chamber and the condensation of vapor in the condenser. The findings suggest that CFD is a valuable tool for simulating and forecasting the flow dynamics in a water distiller. Additionally, the study explores the impact of adjusting the empirical coefficient in the Lee model. It has been shown that the flowrate of the pure water in the storage bottle increases with the increase of the value of this coefficient. We found that a coefficient value of 1.4 yields a flow rate that is closest to the manufacturer’s specified rate of 1 L/h.
