This research effort provided a process and results for the prediction of the pressure gradient in the vicinity for a circulation controlled vertical axis wind turbine (CC-VAWT). The pressure gradient was determined using the Computational Fluid Dynamics (CFD) software, Fluent. The pressure gradient was then compared to the current commercial standard horizontal axis wind turbine (HAWT) the CC-VAWT and was shown to produce a much lower pressure drop within its immediate vicinity of the wind turbine. This difference shows evidence towards a potential solution for the current negative effects that the wind turbine industry is having on bat populations, namely barotrauma.
