Ansys Fluent transient pipe flow

  1. Nov 7, 2017 #1

    I am doing a relatively simple problem, but i cant initialise it.

    I have hot water at 400K moving inside a copper pipe at 300K. I would like to see the time it takes for the copper pipe's temperature to increase to 400. However I cant seem to initialise the temperature of the pipe, as in all the plots its temperature starts at 400 at t = 0s.

    I simply have a hollow pipe filled with a fluid. In the boundry conditions of the pipe I thermally couple it with the fluid. In standard initialisation I tell the solver to compute from pipe wall at 300K, but no avail.

    Can anyone please help. Its a basic problem but has taken me days now.
