Boundary Layer Theory. Introduction Let’s start understanding the overview of the topic by a simple example. Now, imagine that you are watching a moving crowd from bird’s eye view. And you will observe sometimes that apart of crowd is moving fast and a part of crowd is moving slowly with this reference you can imaginarily draw boundary differentiating crowd on basis of their relative velocity this theory of boundary’s in flowing fluid is said as boundary layer theory. Fig :(a) Image reference : https://www.nuclear-power.net/nuclear-engineering/fluid-dynamics/boundary-layer/ Let’s take a look at above diagram ( Fig :(a) ) In above diagram a flow of fluid on a flat plate is shown. Here in this diagram the fluid ...
