Numerical Investigation on Fluid Flow Characteristics of Thin Film Evaporation Meniscus Region in the Rectangular Groove

The fluid flow characteristics of thin film evaporation meniscus region in the rectangular groove were investigated in this paper. An analytical solution of the pressure distribution within the meniscus bulk region, where the interface is dominated by surface tension was found via a coordinate transformation and the Galerkin Method. The pressure distribution and the velocity distribution of thin film evaporation meniscus region in the rectangular groove were calculated and analyzed. The results show that decreasing the contact angle could improve the flow property of the meniscus region in the rectangular groove. The results investigated in this paper can help understanding the mechanism of thin film evaporation for the further study.
