Question

10 Flow over an elliptical cone at zero angle of attack, the fluid properties are a function of how many elements?

(a) 1

(b) 2

(c) 3

(d) 4

I had been asked this question during an interview.

My question comes from Cones at Angle of Attack in division Three-Dimensional Flow of Aerodynamics

Answer 1

Correct answer is (b) 2

Best explanation: Unlike right – circular cone kept at zero angle of attack with respect to the free stream, fluid properties over an elliptical cone at zero angle of attack is dependent on two factors – Azimuth angle and polar angle.
