Hi I got a problem while using ANSYS CFX , the case I'm going to run is an aircraft cruising at 10 km high with mach=0.75. Usually when I was doing with the CFD code like SU2 or the inhouse code of our lab, I could easily set the reynolds number to be a certain value. Reynolds number is one of the three similarity parameters, with the other two as mach number and the scaled shape.
However, in CFX, is there a way for me to directly set the Reynolds number that could match the case ? If not, I guess I have to change the gas property to indirectly tune the Renolds number, then how could I do it ? |
