摘要
本文提出了环形双侧吸气新型高效液气射流泵。运用液气两相流体力学基本理论和准二维分析方法,导出了该泵的基本性能方程、动量修正系数及阻力系数的表达式,以及基本方程的简化式。提出了确定该泵最优工作及几何参数的计算方法,通过试验对上述理论进行了验证。
A new type of high efficient liquid-gas jet pump with ring-shape noozle and two-side suction gas is presented. Based on fluid mechanics of the two-phase flow and quasi two dimensional analysis method, the fundamental property equation of this pump and its simplified one, and the expressions of modified and resistance coefficients are derived. The calculation method of determining the optimum work and geometrical parameters of this pump are presented. The above theory is verified by experiments.
