how to calculate reynolds number

Bhanu24 · July 15, 2016, 15:52

Hi all..!!
I am simulating a 2D airfoil S823 in Fluent (transient 6 sec) for different inlet velocities and different angle of attacks. The chord length is 1 meter of the airfoil. How do i calculate the reynolds number for the different cases (velocities and Angle of attacks). I am using K-omega SST turbulence model. Any help will be highly appreciated.

This isn't a Fluent problem but a simple straightforward calculation following the definition of Reynolds number. Do this in excel or a calculator or anything.
