Ah so you plan to use an ABL inlet? Thats going to be much more complex to calculate.
Yes you are able to do that. However of course its a little complicated. So you should know that every calculation is based on your velocity and the other critical factor is your ABL velocity. Do note that these two are different and you will need to read through literature or sample projects like here in order to get out the equations you need. I’ll give a brief overview here.
You have 3 primary equations, one for velocity, one for turbulent kinetic energy (TKE) and one for dissipation depending on the model used. For the last one, you generally pick between k-esp or k-omega SST. For k-esp, there is a specific equation for deducing esp for a given TKE and the TKE relates back to your velocity. For k-omega SST, your omega values relate back to the esp equation.
All these values are related directly to a specific layer at a specific height and at a specific velocity. Now with your dual component wind velocity, you effectively have to do this set of calculations twice.
I don’t think its very clear from this over simplified generalization of how to do it, you will need to read through and understand every single component of the calculation as seen in the project i referenced. Such is the pain of trying to get a proper ABL inlet. So do let me know if after some time you’ve looked through all the information and am still not sure.
