how to set initial pressure in a closed system

March 12, 2007, 07:43

hi

I am modelling a refrigeration system consisting of compressor , aftercooler, regenerator ,cold and hot end heat exchanger connecting tube and reservoir. This is a complete closed system.I want to set initial charging pressure of the whole system at 50 bar.Means when time t=0 whole system is at 50 bar.When reciprocating compressor piston moves back and throgg the compression and expanssion of gas takes place. Please help how to set this initial pressure.

Did you try initializing your flow field? Solve->Initialize-> Initialize -Phil
