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 |

Hi
What is your fluid for experiment and simulation? |

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