Good job Dr, I have questions in this topic, 1- How to calculate the local the local nusselt number in 3d tube (midle for exemple)? 2- How the average nusselt number of the fluid domain in 2d and 3d tube? 3- how to plot wall temperature function of axial position in 3d tube?
No. The Nu number will change across the wall since the temperature difference is changing as you move at the wall. In that case, you need to work out with average Nu number

2- How the average nusselt number of the fluid domain in 2d and 3d tube?
3- how to plot wall temperature function of axial position in 3d tube?
What should I do if I apply wall temperature instead of heat flux to find Nu=3.66?
Thanks
Can I follow the same procedure for 3D PIPE?
Sir can we follow same step for 3-d model and if heat flux 250 is enough ??
For fully developed region, the nusselt number will be the same throughout the surface wall ?
No. The Nu number will change across the wall since the temperature difference is changing as you move at the wall. In that case, you need to work out with average Nu number
Thank you for sharing this information
how about turbulent sir?
