Hi Kiran,

I've been trying to simulate the case with komega, but I could not because he always showed me error when simulating.

I upload the case to the next link because I do not know what...

Hi Kiran,

I used the turbulent intensity of 0.05, for kepsilon, because I used the same formula k = 1.5 U · U · I · I = 1.5 · 0.01 · 0.01 · 0.05 · 0.05=3.75e-7, but you made me think I should use...

I'm doing the simulations with turbulent flow, so I am using RAS model with k and epsilon. The flow is turbulent Reynold's 10 ^ 4.

The Cd and Cf are average values.

In the figure below, you can...

Post flat plate with turbulent model

Hello everyone.

I write because I am studying a turbulent model in a flat plate with an inclination of 30 degrees, but I can´t get the values ​​of Cd and Cl found in the literature.
