We are working on CFD simulation of PCHE using Ansys Fluent. While , performing this simulation we used periodic boundary condition and nist database REFPROP real gas co2 for obtaining temperature and pressure dependent fluid properties.
We are getting the above error while performing the simulation.
Kindly lookinto this and please advise. The screenshots are attached wih this.
Hello,
This is not answer to your question but just to know what you mean by PCHE and what application you are trying to use this for?
Thanks
Pche means printed circuit heat exchanger which can also be micro channel heat exchanger. It is a compact heat exchnager commonly used bcoz of high surface area to volume ratio. They are commonly fabricated using photo chemical etching
Hello,
Could you solve this error 203 tprho (density)? please let me know if you could find a way to solve it
No, we started using CFX with polynomial functions for temperature dependent properties
It depends on your simulation and working fluid phase. For now your simulation runs in vapor phase. So, you need to change it to liquid phase (if you have just one phase). just use set-phase in fluent to change your phase to liquid
