Question

According to Eulerian approach, which of these is correct?

(a) Both location and fluid move

(b) Location moves and fluid is stationary

(c) Both location and fluid are stationary

(d) Location is stationary and fluid moves

I got this question in an online quiz.

Origin of the question is Governing Equations topic in section Governing Equations of Fluid Dynamics of Computational Fluid Dynamics

Answer 1

Right answer is (d) Location is stationary and fluid moves

For explanation I would say: According to Eulerian approach, a particular location is chosen and the fluid flows past this location. This flowing fluid is analysed.
