Default Contaminant Concentration
Posts: n/a
Hi! I have a project where i have to model the concentration of contaminants in a road tunnel, using different methods of ventilation. I am having difficulty with writing a UDF to model the concentration. Any help would be appreciated!

Would you mind giving the details about it. As I know, there is a model about speices transport without reaction in Fluent. Maybe you can use that model to simulate the transport of contaminants.

Basically I have to solve an equation relating the concentration of contaminants in the x-direction to a set of variables including inflow velocity, outflow velocity, pollutant concentration in inlet air, deposition rate, etc. The next step is to then display the results, and then to try to solve equations for the 2D and 3D cases. I will try to get a copy of the equation I am using available to view.

Any help will be much appreciated Alex

azna is on a distinguished road

I need to add nitrogen to water. I don't know how to write UDF for it and adding concentration. I was wondering that is there any tutorial for some case similar to mine ?
