Heat exchanger simulation
Thread Content
Friends, there’s a question that has been bothering me, and I hope the experts here can help me find an answer. I have a low-temperature plate-fin heat exchanger that is used to convert liquid oxygen into oxygen. We don’t care about the medium on the hot side (nitrogen or anything else will do). We know that the critical pressure of oxygen is around 5.13 MPag, and its critical temperature is -119°C. Assuming the pressures of liquid oxygen are 5.0 MPa, saturated, and 5.2 MPa, saturated, is there a significant difference in the heat exchange area between these two types of heat exchangers? Are there any major design differences when the heat exchangers operate near their critical conditions?

There is a significant difference, involving phase transition.
