TALK=T;RUN( 1, 1) DISPLAY TWO-PHASE FLOW IN A BIFURCATION The turbulent two-phase flow in bifurcating channel is solved here on Cartesian grid by "cut-off" technique of PARSOL. The case is aimed to demonstrate the PARSOL performance for two-phase flows with a phase slip. The demonstration case considers the turbulent flow of dispersed air/water mixture in the branching channel designed as two-dimensional asymmetrical bifurcation. In this case the pressure distribution, phase volume fractions, velocity fields of air and particulate water have to be calculated.
