Flow over an airfoil

Objective

To simulate NACA air foil For the angle of attacks 0,2,4,6,8,10 compare the lift and drag forces.

Here we used NACA airfoil (a18-il)A18 (original) data to design the airfoil

For the angle of attacks 0

Lift at (Y) & Drag force at (X)

For the angle of attacks 2

Lift at (Y) & Drag force at (X)

For the angle of attacks 4

Lift at (Y) & Drag force at (X)

For the angle of attacks 6

Lift at (Y) & Drag force at (X)

For the angle of attacks 8

Lift at (Y) & Drag force at (X)

For the angle of attacks 10

Lift at (Y) & Drag force at (X)

Canculasion

By the above simulation we see that as we increse the angle of attack lift force and drag force also increase.
