An improved method for calculation of interface pressure force in PLIC-VOF methods
چکیده انگلیسی
A method for the application of interface force in the computational modeling of free surfaces and interfaces which uses PLIC-VOF methods is developed. This method is based on evaluation of the surface tension force only in the interfacial cells with out using the neighboring cells. The normal and the interface surface area needed for the calculation of the surface tension force are calculated more accurately. This method is applied on a staggered grid and it is referred to as Staggered Grid Interfere Pressure calculation method or SGIP. The present method is applied to a two-dimensional motionless liquid drop and a gas bubble. In addition, oscillations of a non-circular two-dimensional drop and a bubble due only to the surface tension forces are considered. It is shown that the new method predicts the pressure jump at the interface more accurately and produces less spurious currents compared to CSF, CSS and Meier's methods when applied to the same cases.
