Incidence Angle Effect on the Behaviour of a Flow around the Turbine Blades

Our work involves a numerical simulation of a turbulent flow that crosses a turbine blade for different orientation angles using a computational fluid dynamics (CFD) code. The turbine's performance mainly depends on the characteristics and efficiency of the blades for optimal orientation angle position. The numerical simulation is based on the finite volume method for the differential equations discretization; different schemes have been used to solve these equations such as first upwind, second upwind, and power law. The turbulence model used in this study is the standard k-epsilon model. The equations governing the flow are solved by the Semi-Implicit Method for Pressure-linked Equations SIMPLE algorithm. The results obtained allow for identifying and characterizing the flow around the blade by plotting the dynamic field, the pressure coefficient, and the Mach number.
