I am using FloEFD to simulate natural ventilation in building. Through my search in papers, I found that the other commercial software use turbulence models like standard K-e, RNG K-e and SST K-w to solve the equations. In this case, the previous studies compared these models with field measurement to validate and choose the best model for further modeling and simulation. However, I could not find the turbulence models which establish in FloEFD software to solve equations. My question is what turbulence models does FloEFD software use for simulation? I appreciate your kindly respond in advance.
