Question

Which among the following have similar fluid streamlines?

(a) Geometric similarity

(b) Kinematic similarity

(c) Dynamic similarity

(d) Conditional similarity

This question was posed to me in homework.

This key question is from Similitude topic in section Dimensional and Model Analysis of Fluid Mechanics

Answer 1

Right option is (b) Kinematic similarity

Best explanation: In kinematic similarity, fluid flow of model and real-time application takes place. Here, the model and the real application must undergo similar time rates in motion changes. Thus, it has similar fluid streamlines.
