Sir, I have done the wind tunnel experiment and got the coefficient of pressure values as 2,3,4. when i did de same thing in cfd(fluent) i am getting de coefficient of pressure value as 600 and around values for speed of 25 m/s.I know that de value of Cp should be less than 1.Now i dont know where i am wrong. I have taken 5 trials in wind tunnel but i am getting de value as mentioned above. please help me to solve this problem
