From experimental data on eight common air diffusers, authors developed simplified methods (the box method and the momentum method) to describe air flow and temperatures in the air jet that can be used as imput data for room air flow CFD calculations. The box method is appropriate for most of the diffusers. The momentum method gives good results for five diffusers. As it is simpler, authors recommend that it is used whenever applicable.
