I am simulating double pipe heat exchanger with helical fins on the outer surface of the inner tube. I have selected SIMPLE scheme with second order upwind method for energy, momentum and turbulent. Also, residual for continuity has been applied as 1e-05 and for momentum, energy and k-epsilon (for turbulent) residual are applied as 1e-06. The hot and cold fluid inlet selected as velocity inlet and outlet for both fluid has been applied as pressure outlet.&nbsp; In initialisation turbulent kinetic energy is 0.001 and turbulent dissipation rate is 1. I have performed 1000 iterations. The energy residual is converged however, continuity residual is not converged. Any suggestion would be appricieted.
