Experimental Research On The Outlet Characteristics Of Flow Field And Energy Consumption Of The Local Generator

Swirling flow in pipe is three-dimensional flow form.It's velocity flow field can be decomposed three components:axial velocity,whirling velocity and diameter towards velocity. Swirling flow is widely used in industry, such as in jet technology, combustion technology, pneumatic transportation, hydraulic flotation etc. Now, There are three kinds of means in the application of sand exclusion by spiral flow, the vortex tube sand exclusion, the sand funnel and the spiral flow in the horizontal pipe.The vortex tube sand exclusion was used to breed out the traction load that mains exist in the bottom of channel. The way of the sand funnel make use of separating mechanics of spiraling flow to breed out the sediment of the channel. The spiral flow in the horizontal pipe can generate the spiral flow to transport sediment according to the way of equipping the guide blade in the middle of the pipe. The Preceding two ways have been used of engineering practice, the spiral flow in the horizontal is a new way of energy-saving and high efficiency which proposed lately to breed out sediment, now it still in the experiment research phase.Through experimental studies, the characteristic of swirling flow in pipe was discovered and studied . Some individual projects were numerical caculated. Finally, the resisting peculiarity was analyzed and experimental investigation. The main research,method and conclusion are as follows:1. It has researched the hydraulic characteristic of flow field through model...
