![]() ![]() The pressure drop was of the -10^4 order,which is not even close to the reference measurements. I have one reference where he applies rotational periodicity to the sides of that one single strip.I went ahead with the reference, but I got absolutely wrong results. I can understand that a transnational periodic boundary condition can be applied between the inlet and outlet of one strip of the fin, but I am not sure as to how would the sides of the fin can be modeled. ![]() Since the fins are arranged in a helical pattern, a single helical strip of one helix pitch length is to be modeled. The internal fins have a certain helix angle and there are a number of fins. My goal is to study the pressure drop in the tube for different combination of number of fins, fin height and fin width.
