Question

Conical flow is an example of which of these flows?

(a) Axisymmetric flow

(b) Two – dimensional flow

(c) Flow symmetrical about x – z plane

(d) One – dimensional flow

I had been asked this question in class test.

This intriguing question comes from Physical Aspects of Conical Flow topic in division Linearized and Conical Flows of Aerodynamics

Answer 1

The correct option is (a) Axisymmetric flow

For explanation: The conical flow is symmetric about a particular axis hence its flow properties such as pressure, density remain the same in plane which passes through a symmetric line. The flow properties depend only on radius r and the axis hence it is known as axisymmetric flow.
