Hi all, I'm simulating a wind turbine rotor..which kind of far condition should be best?for example,imagine a free stream tube with the rotor blades inside..which kind of conditions would you use at the outflow and at the lateral? i used outflow condition,because i don't want to use pressure far field to not use energy equation..do you think it is a good choise? outflow boudary condition impose some gradients at the boundary? thanks
