Well, I didn't check the velocity field, but I can. So I will check and upload that later. I think maybe it will take some time.

Yes, I set all regions to have the same pressure. But I believe I should check my simulation setting again. I will check again with your suggestions such as speed or 1D problem. Thanks for your reply.

That is very helpful to understand my simulation. Thank you and I will more think about your reply.

Also my mistake. It is not abnormal gas. The gas in the simulation is an ideal gas.

Thank you for your answer. I agree the simulation doesn't show the noticeable bulk convection. So do you think that simulation doesn't look like real nature? I hoped to model real gas which is around us.

gas can move. so there is convection and conduction. I don't consider radiation.

Thanks. That is my mistake. The fluid dynamic is right.

This is a fluid dynamic simulation. The top area has 100 degrees Celsius. The bottom area has 0 degrees Celsius. And both are filled with an ideal gas which is 1-atmosphere pressure. Two areas are connected through the left small line. Another part is blocked. So heat transfer can only happen...
