Abstract
In this paper, an Interface-Tracking method combined with the Moving-Grid Finite-Volume method is presented for simulating the free surface flows. Free surface flows are important from a point of view of engineering. For example, sloshing flow in tanks, mixing in vessels, jet from nozzle and injection molding are free surface flows. Many numerical methods are presented for free surface flows. These method can be classified to two approaches, interface-capturing method and interface-tracking method. We use Interface-Tracking Method. In the Interface-Tracking method, the calculation grid is moved and deformed according to the movement of the free surface. Surface height equation is used for the free surface shape determination. The purpose of this paper is to extend the Moving-Grid Finite-Volume Method to free surface flows. The main advantages of this method is simple treatment with free surface and satisfying physical and geometrical conservation laws. We applied this method to some flow cases with free surface. As test cases, sloshing flow in a tank is presented. Numerical results show that the present new Interface-Tracking Moving-Grid Finite-Volume method is very accurate and have a promising feature for moving boundary problem with free surface.
