摘　　要：采用有限控制容积法和Ｋ－ε二方程紊流计算模型，对喷射泵喉管内流场进行了数值模拟，得到流场的参数分布，为采油喷射泵优化设计奠定了基础。同时采用激光测试ＬＤＶ技术首次对喷射泵内流场进行了二维测试，对计算结果进行了验证，结果表明，Ｋ－ε紊流模型可用于喉管内部分流场的计算，在适体坐标下可进一步推广到喉管入口处及扩散管部分流场的计算。The finite volume approach and the two-equation K-ε turbulence model are applied to study the flow-field of jetpump throat. The vector plot of the flow-field is obtained.The results can give a theoretical fundament for the optimization design of jetpump and improving the operation efficiency. The laser doppler velocimeter (LDV) was utilized to test the jetpump flow-field in the two-dimention.It is verified that the methods are available for the study of throat flow-field in jetpump.
