CFD STUDY FOR FLOW BEHAVIOR OF AEROFOILS

The conception and examination for the aerofoil geometry have been executed in the current work to evaluate the behaviour of the flow in terms of the velocity and pressure lineation. The aerofoil geometries are opted to be of new aerofoil type of NACA 8412 series. The aerofoil geometry was analysed for a constant angle of attack along the total length. This evaluation was done for the angle of attack ranging from 0o to 20owith 5o interval for each model. The inlet velocity for the flow along the surface of the aerofoil geometry was taken varied from 7.5m/s to 10m/s with 0.5m/s interval for each model. The plot points for the geometries are generated using the Auto CAD for different angles. The further simulations and evaluations were executed using the Ansys Fluent software. On evaluating and considering the variable conditions, the optimum values are obtained for the aerofoil at 15o angle of inclination at an inlet velocity of 9m/s. The software generated results when compared to the regression data generated ascertained to be in a good correlation with each other
