低雷诺数下临界流文丘里喷嘴的背压比研究
Study on Back-pressure Ratio of Critical FlowVenturi Nozzle at Low Reynold Number
摘要
Abstract
By the analysis of the foreign research results on the critical flow Venturi nozzle at low Reynolds abroad, the effect of spread half-angle, curvature radius and area ratio on the back-pressure ratio was observed in combination with some proposals on maximum back-pressure ratio of critical flow Venturi nozzle at low Reynolds number and ISO 9300 ∶2005(E) on geometric size of toroidal throat critical flow Venturi nozzle. From the observation, some inspiration was obtained. A testing program that the back-pressure ratio is effected by spread half-angle and curvature radius is put forward.关键词
