no one is replying me...zzzzzz.. tis article have show that the airfoil section for ceiling fan blade is practical

Anyone can show me how the velocity diagram at the inlet and outlet of a airfoil section ceiling fan blade?

For the final year project that i am doing, I need to design a high efficiency ceiling fan blade with airfoil section, tapered and also twisting. Can anyone tell me how can i obtain the optimum pitch angle for different section of my ceiling fan blade?
