Dear researchers, I am simulating an unsteady turbulent flow (ideal gas) in complex geometry, and I want to calculate the Reynolds number of the flow. At the entrance of the field, a pressure of 0.25MPa, is imposed. My question is: how can I calculate the Reynolds number of the flow inside computer domain?
SERRARMarch 16, 2021 at 12:34 pmRobAnsys EmployeeTreat the solver result in exactly the same way you would experimental data. How would you do the calculation there?
March 16, 2021 at 3:57 pmabd fsSubscriberDear Rob I have no experimental data, I only have the results digitally simulated by Fluent.
If possible, do you have any recommendations for finding the Reynolds number?
Best regardsMarch 16, 2021 at 5:04 pmRobAnsys EmployeeWhich are a simulation of a real system. In the real system how would you calculate Reynolds Number?
March 16, 2021 at 6:30 pmabd fsSubscriberDear Rob Thank you very much for your quick responses. I want to share with you my domain of computation to give you a vision of what I'm talking about.

Thank you so much for your help Best regards SERRAR

Do you have any idea how can I calculate the number of Reynolds?
Best regards SERRAR

March 18, 2021 at 2:54 pmabd fsSubscriberDear Rob Since I have a complex domain, I have divided it into several subdomains, which increases the quality of the network.
Beste regards SERRAR
