I'm simulating a natural convection in fluent using bossinesq approximation. I was told that the temperature gradient of the system cannot be large. So, what is the range of the tempareture gradient that acceptable to use in fluent?
In experimental works, Rayleigh number of the natural convection is varies by the change of the temperature gradient. In CFD, what variable can we change to increased the Rayleigh number as the temperature gradient cannot be increase too much? |
