- A cylindrical pipe is split into two parts, the space in between the split parts is filled by pipe material. There is conduction heat transfer between the split sections of the pipe. In one section hot Ethylene glycol is flowing & in another part water is flowing. The change in temperature of both sections has been analyzed. It works as a counter-flow heat exchanger with partial surface heat transfer.

Dear Sir, I have one question about the in inlet and outlet boundary conditions. The molten salt enter a pipe with 5m lenght and 20mm diameter and 500k . The pipe is made of stainless steel. The heat flux is 800,000kW/m2. So how much should be the inlet flow rate up to we receive the outlet tempereture 800K. It will be highly appreciated when you guide e the boundary conditions in inlet and outlet in such a case. Thank you.

How many iterations does it takes for the solution to converge?
it will not be converged , as you can see x, y velocity, continuity already straight line, only variation is the z velocity, try to keep the z-velocity residuals upto 1e-3 to get the convergence.
