The plate evaporator is now becoming more dominant in the desalination market

but due to the complex heat transfer mechanism of two-phase flow

there are some difficulties in investigations on two-phase flow in the plate evaporator by simulation.Thus

a three-dimensional physical and mathematical model for the plate evaporator with corrugated plate was developed in this paper.The characteristics of flow and heat transfer of seawater through evaporation process in the above corrugated plate evaporator were researched by computational fluid dynamics(CFD) method

to reveal the effects of corrugated plate inclination angle and corrugation depth on seawater evaporating performance.The results show that

because of the existence of contacting points

strong turbulent is formed when the seawater flows down.In the flow direction

the water vapor's mass fraction continuously increases while that of the seawater decreases gradually.The greater corrugation depth is better for diffusion of the vapor evaporated from seawater.The advantage of greater channel width over evaporation shows obviously at the larger inlet velocity.The heat transfer performance of the corrugated plate with inclination angle ? of 60° is greater than that with ? of 30°.The research can provide reference for development of the low temperature multi-effect evaporation desalination.
