Air Flow over a Three Element Airfoil and Main Airfoil

Simulation of air flow over the three-element airfoil using Ansys Fluent. Estimation of lift and drag forces for this configuration was done. Compare these values with those from the case without slats or flaps. The angle of attack (AoA) is 4 degrees and the freestream Mach number is 0.19.

Boundary Conditions

A steady state simulation was done using gas with constant density as fluid. The flow type was set to be segregated Turbulent flow. K- Omega Turbulent model was used.

Inlet Velocity was set to 65m/s

AOA- 4 Degrees
