I separated the tube in two parts so i get a finer mesh on the part before the flow develops fully. So i get a weird temperature drop on 0,4 meters the point the two parts separate (photo = https://imgur.com/a/AFOaIOZ) noted that i used share topology for the two parts. This is my mesh https://imgur.com/a/I6HIDEd https://imgur.com/a/XUvC5pz any suggestions? I assumpt that the flow develops fully at 10*D=0,3 m how can i show the boundary layer of velocity and thermal in contours?
