Atmospheric pressure gradient
I am trying to simulate the rise of an humid thermal in the atmosphere.
Previously, i want to obtain the solution for the pressure that Fluent gives for a thermal stratified atmosphere.
The material is air (ideal gas). Th left boundary is symmetri. The bottom is a wall. I donīt know how boundary set in the right and the top side (outflow is not available with commpresible flow).
The temperature in the domain is: T(z)=288.15-6.5*z/1000
I am simulating with a RNG k-e turbulent model.
In summary, i need to obtain the pressure gradient in the atmosphere for this temperature gradient. How can i do it?
thanks in advance
In summary, i just wanīt to obtain the hydrostatic pressure.
