Determinação do coeficiente de pressão de um corpo cilíndrico e do perfil Clark Y em túnel de vento

Abstract

The analysis of the external flow, that is, flow over blunt and streamlined bodies allows identification of the pressure distribution, the appearance of the drag and lift forces and also the moment generated. The pressure distribution on body is usually defined in terms of a dimensionless parameter called Pressure Coefficient. In this work we evaluated the wind tunnel of the Flow Machines Laboratory at Federal University of Technology - Paraná - Campus Pato Branco using a cylindrical profile and a wing profile type Clark Y. Although the results obtained in the wind tunnel had features similar to that found in the literature, values, for example pressure coefficients of the cylinder, were relatively higher.
