Numerical investigation of effects of inner cone on flow

Numerical Investigation Of Effects Of Inner Cone On Flow

Aug 07, 2018 From Fig. 11 it can be concluded that an increase of the inner cone diameter causes the flow to be limited to the walls, and subsequently the flow is not allowed to form the secondary vortex. On the other hand, increasing the height of the inner cone while keeping its diameter constant affects the vortex flow at the cyclone bottom.

Understanding What is Cone of Depression and How it is

Understanding What Is Cone Of Depression And How It Is

A Cone of Depression is formed where the water table sinks at an exact point because of heavy pumping. Water is extracted out of the ground which leaves an airy space around the soil particles. If the pumping rate is faster than that of water that is flowing in, it results in the drawdown of the water table at the location of the pump.
