Abstract:

The study presents a consideration of some of the problems of a two-phase flow theory in an effort to consider the problem of the separation of a two-phase fluid mixture in a cyclone separator. A simplified model is proposed and estimates of the rate of discharge of the heavier component are obtained. The discharge mechanisms are discussed and the model indicates the importance of secondary flows in heavy fluid discharge. It indicates that, at most, the secondary flows are only aided by gravity not due solely to gravity, as it was previously thought. An experimental separator was designed and built. It was operated in an inverted position to indicate that the secondary flow could overcome an unfavorable body force. Tests were run on this cyclone when operating in a normal position to determine the effect of the variation of certain geometric factors and operating conditions on the flow and separation of a two-phase mixture. Separation efficiency and pressure drop information is presented for a wide range of operating conditions and geometric configurations. Author
