Estudo de efeito da turbulência em uma placa plana com cavidade usando o programa Ansys student

Abstract

Turbulence is a undesired effect that happens in aeronautics. With greater turbulence comes also a greater drag, which makes the airplane to burn more fuel. Not only that, but computational simulations do not take into account minor imperfections that occur during the aircraft manufacturing, generating discrepancies between theoretical simulations and practical results, resulting in manufacturing having big error margins. Whit that in mind, the Group of Acoustics, Turbulence and Transition (GATT) from EESC - USP Sao Carlos initiated studies about the effects of a gap in a wing. Due to the particularity of such case, GATT have done computational studies based on models developed by GATT itself. To provide an independent theoretical result, this work tries to accomplish a simulation of the same case using a commercial software available for free, ANSYS Student, to verify if the computational results agree with the experimental ones obtained by GATT.
