Thermal stratification improvement
I have simulated the temperature distribution for ventilation in a room and I have got some crude results. I require some good stratification visualisation for the inferences. I have refined it with fluent meshing for 350,000 cells as given from literature. The solution converged. I have attached the crude results I got and the expected stratification I require. Is there some error I make or is there any improvement required?? Kindly suggest corrections or methods to improve the stratification I obtained.
