Research On The Characteristics Of Flow Field Of The Internal Local Generator

Sediment transportation in spiral pipe flow is a new method of sediment transportation .The merits of high concentration low energy long distance and non-deposit of spiral pipe flow have amplitude foreground. So ,studying the basical theory is essential,therefor in this paper, research on the characteristics of flow field of the internal local generator ,which gives theory's basis for the equipment designed.Swirling flows in pipe are generated by three ways: tangentially inletting medium, guiding fluid by vanes with acertain angel in pipe were studied in this dissertation. Though three different flux of experimental studies the velocity and the vorticity were messured , analysis the characteristics of flow field.Fllowing is the major contents of the paper:...
