同型管道双车在不同流量条件下的缝隙流轴向流速特性研究
Study on the Characteristics of Slot Flow Velocity at Different Flow Conditions of Same Double Piped Carriages
摘要
Abstract
In order to enrich the theory of piped hydraulic transportation and promote its industrial application,the characteristics of slot flow velocity at different flow rates of the same pipeline are studied.The results show that:(a) the flow rate is increased with the increase of flow rate;(b) the axial flow velocity of the gap flow is increased along the direction of water flow,then tends to be stable and finally increased gradually;(c) at different angles of same measuring ring,the axial velocity variation of slit flow is low,and the minimum value of velocity is obtained when the angle is 180°;and (d) with the increase of the radius of measuring ring,the flow rate of front and rear cross section of piped carriage is first increased gradually,then tends to be stable and finally decreased gradually.关键词
