Example

An incompressible, inviscid flow past a circular cylinder of diameter d is shown below. The flow variation along the approaching stagnation streamline (A-B) can be expressed as:

x

y

A

B

UO=1 m/s

R=1 m

Along A-B streamline, the velocity drops very fast as the particle

approaches the cylinder. At the surface of the cylinder, the velocity is zero (stagnation point) and the surface pressure is a maximum.
