Hello, I am new to Molflow and need some guidance on how to simulate high-velocity, parallel flow into a chamber.
I have a body, similar to a tube with an inlet and an outlet. Gas is flowing into the inlet of the body at around 1 km/sec and each incoming particle should be mostly parallel. The body of the tube is cooled down to about 20 K and I’m trying to figure out how many particles will reach the exit.
Thank you for any help and guidance you can give!
Hello Lucas,
Due to a problem with notifications, I’m only reading it today.
If it’s still relevant:
You would use the “Moving parts” feature in Tools menu to set up an 1km/sec initial vector of speed, then assign it to the inlet by enabling “Moving parts” in the facet advanced settings:
Hi Addy,
Thank you for the reply! That helped a lot. Could I also ask about how to set the inlet gas flow to parallel flow? Rather than something like a Lambertian distribution?
we’re trying to model the flow of an incoming gas (1 km/sec) into a cold chamber (20 K wall temperature) and basically see how much of the gas is captured on the walls of the chamber, and how much makes it through the chamber and exits out the back.
If you add velocity of 1km/sec you already collimate the flow quite a lot.
Additionally, you can set Cosine^99999 type desorption instead of cosine for further collimation.
