Hello Marton,
Happy New Year!
Based on your reply and the TOPIC, I have gained a deeper understanding of pressure and throughput calculation, as well as vacuum knowledge. Thank you very much!
Since I didn’t see the answer to the last question in the POST, I still have some remaining questions. Here is my understanding of it:
For a non-isotropic situation, such as a stream of particles, we can use momentum exchange to calculate the pressure on a real wall. For a transparent wall, using density and the ideal gas law is a useful way to calculate pressure, and the ‘double counting’ method is no longer applicable.
Does Molflow still use ‘double counting’ to calculate pressure for transparent surfaces? If so, should I manually convert density to pressure to obtain the correct pressure value in non-isotropic situations?
Best regards.
