Abstract

A finite-volume based computational model for one dimensional, unsteady two fluid flow in a pipe E.R. seol, D.-D. ~ e e ' & S. paramewaran' 1 Samsung Electronics, South Korea ' ~ e ~ a r t m e n t of Mechanical Engineering, Texas Tech University, USA Abstract This paper describes a computational model based on finite volume method to model the two-phase flow that occurs in a standpipe. Both phases are treated as continuums. Pressure field, which is treated as common to both fluids, is obtained using the SIMPLE algorithm. Field variables are stored in a staggeredgrid fashion; pressures are stored at the center of a cell while the velocities and void fractions are stored at the cell faces. Separate momentum equations are used to calculate the velocities for each phase and thus allowing slip. Pressure is assumed to be of the same value for both phases. It is assumed that the resistance due to the motion of the second fluid on the first is proportional to the velocity difference (slip velocity) be
