ABSTRACT

It is the intention to deal with certain flow fields which are special in the sense that the experimentation in such fields requires a slightly different approach than those employed in other flow fields. When dealing with special flows like rotational flows even the coordinate system employed has to be different from that used for studying general flows like pipe flow, boundary layer flows, and so on. Rotating flows can be established in laboratories with a rotating tank. In a rotating fluid the boundary layer formed on the floor of the tank has some special significance. In the Ekman layer the frictional forces reduce the velocity and hence the Coriolis force is no longer in balance with the pressure gradient; hence the net transport in the Ekman boundary layer is at an angle to the net transport in the interior.
