How to simulate and track more than two gases

General discussion

Hi everyone

Is it possible to simulate the collision and paths of more than two gas molecules using Molflow?

For example, different intake pipes are used to supply nitrogen and hydrogen respectively, and the adsorption amounts of nitrogen & hydrogen on a certain surface are measured respectively.

Or I just simulate one gas first and record the pressure and then import the background gas?
Can background gas be a dynamic variable?

BTW, can you simulate the adsorption on a rotating surface?

Best regards,
Ivan Lin

Dear Ivan,

Molflow works in the molecular flow regime, thus it cannot simulate collisions. Background gas is a specific exception, where you have a static background gas, uniform all over the geometry, and the simulated gas can alter its path based on collisions (that do not have any feedback on the background gas).

I hope I understood your question well, if not, get back to me,
