heat flux-fluent-value
Hi there, I am modelling a box with 2 inlets and an outlet and with a heater of 30W. I would like to observe the natural convection - temperature changes.

I am using ideal-gas incompressible, laminar flow. t initial is 293K and the temperature of the heater rises to around 460K when I used pseudo transient.

I did the experiment manually and the temperature rose only by 7 degrees. does anyone know why this is happening? tnx

What is your fluid for experiment and simulation?

Air at 20 degrees

Choose Boussinesq model for density. Consider the gravity. Run your case again...
