For the problem where two phase flow is expected to change very slowly in time or not to change, it may be possible to obtain adequate information from an approximate solution based on very large time step. This would be advantageous if a reliable and efficient means could be found for solving difference equations treating all terms by backward differences. This paper describes a fully implicit numerical method and numerical examples for two dimensional incompressible two-phase flow with two-fluid model. The method is an extension of SIMPLEST scheme which is widely used to analyze various single-phase thermal hydraulic problems. Further extension of the method to tree-dimensional analysis and/or compressible two phase flows is also straightforward.
