Within a boundary layer for a steady incompressible flow, the Bernoulli equation

Consider an incompressible laminar boundary layer flow over a flat plate of length $$L$$, aligned with the direction of an incoming uniform free strea...

If $$'x'$$ is the distance measured from the leading edge of a flat plate, then laminar boundary layer thickness varies as

Flow separation in flow past a solid object is caused by

The necessary and sufficient condition which brings about separation of boundary layer is
$${{dP} \over {dx}} > 0$$

As the transition from laminar to turbulent flow is induced in a cross flow past a circular cylinder the value of the drag coefficient drops.

The predominant forces acting on an element of fluid in the boundary layer over a flat plate in a uniform parallel stream are:

A streamlined body is defined as a body about which
