Extension of physical component BFC method for the analysis of free-surface flows coupled with moving boundaries. (English) Zbl 0907.76065
Summary: A newly developed physical component boundary fitted coordinate (BFC) method is extended for the analysis of free-surface flows coupled with moving boundaries. Extra techniques are employed to deal with the coupled movement of the free surface and moving boundaries. After the validation of the extension by several benchmark problems, the method is applied for the first time to the simulation of overflow-induced vibration of the weir coupled with sloshing of the free-surface liquid.
