how can I calculate the Reynolds number of the flow inside computer domain?

      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?

      Best regards,

      Treat the solver result in exactly the same way you would experimental data. How would you do the calculation there?

      Dear 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?

      Which are a simulation of a real system. In the real system how would you calculate Reynolds Number?

      Dear Rob Since you can't open the image, you can just type sweeping jet on google and you will find what I have researched.

      Dear Yasser
      Do you have any idea how can I calculate the number of Reynolds?

      Re number is used for comparison between similar cases at different scale and flow conditions. So, I would look in the literature for similar case .. if nothing is found, I would calculate it at the entrance

      Ah, a bi-stable fluidic oscillator. Make sure your mesh is VERY good.

      Dear Rob Since I have a complex domain, I have divided it into several subdomains, which increases the quality of the network.
