Validation of fully implicit method for simulation of flows with interfaces using primitive variables
MetadataShow full item record
This paper describes applications of the fully implicit procedure for computing flow of two immiscible fluids. Six problems in two and three dimensions are solved to highlight effects of grid size, pressure smoothing, TVD convection scheme and geometric and fluid dynamic evaluations of surface tension force. Free surface and cavity flows are considered in which effect of sloshing, interface merger and splitting as well as splashing are included. Wherever possible, present solutions are compared with results of previous experiments and/or numerical computations. Computational details such as grid size. time step, under-relaxation factors, mass/volume conservation are reported. (C) 2009 Elsevier Ltd.
