Hello,
I’ve just started working on Thermal LBM! I wrote a D2Q9 code for a duct base on D’Orazio and Succi papaer[1]
Velocity profile is ok but the problem is the temperature distribution! The inlet is hot flow and the wall boundaries are cold. the flow gets cold quickly! It is warm just very close to the inlet! I tried for higher velocity but not a visible change in the result. I got tired of checking BC and the whole code over a month!
Could you please give me a suggestion? It would be high appreciated if send me a code to check my code with that!
Regards,
