  Hi,
  I am Ashen and i am doing a CFD modelling of a shell and tube heat exchanger. The model assumes the tube surfaces to be at a fixed temperature of 450C and the shell inlet to be at 300C. However , at the point of contact among the tube and the baffle the temperature doesnt remain at 450C as i have not fixated the baffle temperature at 450C should i be fixating the baffle temperature to 450C . I have attached images of my problem.

  The image of the tube surface is attached after solution converged

  The model of the heat exchanger and tube surfaces which are assigned 450 are shown below

  Remember you're seeing the fluid temperature, so that may not be as warm as the wall temperature.
