Description
Summary:The aim of the present investigation is to obtain and analyse vortex flow field and aerodynamic characteristics of perforated plates at different angles by numerical simulation using OpenFOAM software package. For fully perforated plate’s passive gas injection through the holes close to the leading edge induce separation zone deformation and affect the whole flow structure downstream. Perforation along the leading edge tends to result in more monotonous curves of normal force and pitching moment coefficients.
