The liquid hydrogen pump increases pressure, causing everything at the outlet to vaporize
Thread Content
I would like to consult the experts: I am currently using HYSYS to simulate the pressurization process of a liquid hydrogen pump. The initial pressure and temperature are as indicated in stream 6, with the pressure being increased to 87.5 MPa. I set the adiabatic efficiency to 100%, and as a result the outlet temperature also rose to -212°C, causing the liquid to completely vaporize. In actual industrial applications, the temperature rise shouldn’t be that high, nor could the outlet temperature be so high. I would appreciate some guidance from experts in this field; thank you!

Simulation is inaccurate at extremely low temperatures; to be precise, liquid hydrogen compressed to 87.5 MPa can only exist in a supercritical state
