As for my knowledge is concerned that in the whole field the intial temperature was kept as 375 k while inlet temperature was 390 k and atmosphere temperature was kept as 275 k. Bottom or inlet Wall temperature is always higher than internal fluid domain temperature that's why there is difference of temperature.
Thanks for the video...what if the container is horizontal and flow is from left to right.. should we have to give gravity as -9.81m/s2 ?
If want to take care of gravitational force into account then you must have to take gravity as -9.81 m/s2.
why you have given the temperature as 375.15K as initial values while initializing whereas you have taken the temperature at inlet as 390K?
Yes this is what I couldn't understand
