摘要
借助FLUENT软件,定量研究了结构参数对大气喷射器性能的影响,并对数值模拟结果进行了分析.定量研究结果表明,结构参数对大气喷射器的性能影响显著,合理设计结构参数对大气喷射器性能的发挥非常重要.数值模拟结果显示,大气喷射器喷嘴的最佳位置应在其出口截面距混合室入口截面9 cm处,混合室的最佳锥度为0°,扩压器的最佳锥度为2.4°,喷嘴的最佳喉部直径为1.5 cm.
With the help of FLUENT software to study the influence of structural parameters on the properties of air jet,and the numerical simulation results are analyzed.The results showed that： the structure of the air jet parameters significantly influence the performance,rational design of structural parameters on the performance of air jet is critical.Results show that the best position of the nozzle of the air jet,which installed by unit 1 of Haibowan electric power plant,should be at 9 cm from its exit section to the mixing chamber entrance section,the mixing chamber of optimal taper is 0 degree,diffuser optimal taper is 2.4 degree,the best throat diameter of nozzle is 1.5 cm.
