Question

Which of the following states that the time rate of change of circulation around a closed curve consisting of the same fluid elements is zero?

• A. Kutta-Joukowski's theorem
• B. Kelvin's circulation theorem
• C. Helmholtz theorem
• D. Blasius theorem

Hint:

Kelvin's theorem is fundamental in theoretical fluid dynamics, especially in aerodynamics and weather prediction models.

Answer 1

The Correct Option is B

Step 1: Define Kelvin's Circulation Theorem.
Kelvin's circulation theorem states that in a barotropic, inviscid flow, the circulation around a closed contour moving with the fluid remains constant.
