Study on asymmetric interior corner flow in microgravity condition

Abstract

The capillary flow in asymmetric interior corner consisting of straight vane and curved wall is studied with analytical solution. The concept of equivalent interior corner angle is proposed to convert the asymmetric interior corner model into symmetric interior corner model. Then the governing equations of interior corner flow are established, and based on which the interior corner flow is calculated. This method is used to analyze the capillary flow in cylindrical vane-type surface tension tank with outer vanes. The research can provide beneficial reference to the design of vane-type surface tension tank.
