| الوصف: | Nozzle-to-throat clearance is one of the main factors affecting the injection coefficient of the vacuum generator. The increase of nozzle-to-throat clearance will lead to the aggrandizement of the annular duct area which the driving fluid passes, thereby amplifying the ejector flow rate of ejector tube and the injection coefficient. On the contrary, Keenan [1] obtained the result through the experiment that the injection coefficient decreased as nozzle-to-throat clearance increases, because the accretion in nozzle-to-throat clearance would increase the pressure of inlet plane of the mixing chamber, resulting in the decrease of the driving pressure difference of the driving fluid, hence the injection coefficient diminished. In this paper, the numerical simulation method is used to obtain the optimal nozzle-to-throat clearance parameter size. |
