# Two Phase Flow Calculations

The two phase flow calculation module allows for two phase liquid-gas calculations to be accomplished. Two phase flow occurs in many industrial processes. Examples are petroleum, chemical, nuclear, refrigeration, space and geothermal industries. With this module it is possible to analyze systems where the vapor quality changes with pipe position as well as two phase flow where the vapor quality is fixed. Two Phase flow is many times more complex than liquid or gas flow and it is unlikely FluidFlow will produce answers as accurate as for single phase calculations.
