Drag Coefficient for Ellipse Form (2D)

Ketut Utama

Dear All,

I have studied drag coefficient of a 2D ellipse form numerically. The Reynolds number applied is about 2.5 million and the coefficient is about 0.1 for L/D=6.0.

I do not have any comparisons with other data whether my result is correct. Through textbook, I can only find drag coefficient up to Rn 0.2 million which is about 0.3. If I extrapolated, the coefficient would be about 0.1 and 0.15 which is close to my result. However, I am not really sure if this is correct.

I wonder if anyone does have any data or information about this.

Thanks.
