| 摘 要： | 引射器内部的流动过程复杂,其设计与分析一般都是建立在一维分析和实验基础上的半经验公式上。由于液-液气引射器在实验及数值模拟方面的研究都很少,因此,依托液-液气引射器实验台,在双流体模型的基础上,引入了滑移系数的概念,并建立了液-液气引射器流场模拟的数值模型。通过实验和不同滑移系数下的模拟对比,确定了滑移系数为11%为宜,通过大量的模拟和实验对比验证了此模型的适用性,此结果可为掌握引射器的工作机理、引射器的设计及其优化提供依据。

| Abstract: | The flow in the two-phase ejector is very complex.Limited by experimental equipments and computer capability,not enough work has been done to obtain the ejector inside flow profile of the complex flowing and mixing process and until now the design and evaluation of an ejector usually were based on 1-D analysis or experimental formula.An experimental platform of the liquid-to-liquid/gas ejector was built and some detailed experiments of pumping both gas and liquid synchronously were made.The numerical simula... |
