Information about Fluent Equations from Theory Guide
I am interested in some things that I could not find in the theory guide:
- Gravity is set in operating conditions, and is not included in equations such as the Navier-Stokes equation in the LES model. How do these interact to ensure the eddies are influenced by gravity in the model?
- In the VOF model, the incident wave profile uses Kx and Ky, which are defined as Kx=kcos(theta) and ky=ksin(theta). I can't find what theta is defined as anywhere in the theory guide for these equations?
- For the wave frequency in the open channel flow, it says U is the uniform incident wave velocity. I see no further explanation on how this was defined?
