Hi all,
I am simulating a heat exchanger in CFX. I have data of velocity vs pressure drop. From this data I work out linear and quadratic resistance coefficients. The drop is in one direction only (the z direction in my model) so I specify a streamwise coefficient multiplier of 100 to block the flow in the other directions. What happens to the momentum in the x and y directions as the flow enters the domain - does it just disappear? The data for my heat exchanger is based on an inlet flow solely in the z direction but in my CFX model the flow has swirl before it enters. Therefore I need the CFX model to account for extra losses due to the flow approaching the heat exchanger at an angle. Can someone please help? |
