稀相气力输送水平弯管与文丘里管气固流动特性
Gas-solid flow characteristics in horizontal syphon and Venturi in dilute phase pneumatic conveying condition
摘要
Abstract
Using pressure drop measurement and electrical capacitance tomography (ECT) methods, the flow pattern, pressure drop and pressure fluctuation characteristics of syphon and Venturi pipes were investigated.By effective pressure drop signal of Venturi pipe, statistical evaluation index was constructed to evaluate the powder flow stability.The results show that, pressure drop signals of Venturi is appropriate to evaluate the powder flow stability in different operation conditions.关键词
