Hello,


Ideal gas law is generally used to model compressible flow where density is a function of both pressure and temperature. In such cases, it would be incorrect to assume a constant density (similar to other incompressible flow problems). Here is a screenshot that provides some additional details about the ideal gas law. Please refer to the Fluent Theory Guide for additional information on this.



Hope this helps.


Best,


Karthik
