基于响应面法的射流泵有限元仿真结构参数优化OA

To enhance the suction performance of pneumatic jet pumps and improve drainage and gas production efficiency,we focuse on the single-tube jet pump structure in the Sulige Gas Field.Using ANSYS to establish a simulation model,we evaluate the pump's performance metrics by analyzing structural parameters.Based on the Box-Behnken Design in the response surface methodology,we develope a response surface model with nozzle diameter,nozzle-to-throat clearance,throat diameter and throat length as design variables,and jet pump efficiency as the optimization objective.Through variance analysis of pump efficiency and structural parameter correlation analysis on the response surface model,it is determined that the influence of each structural parameter on efficiency follows the order of:nozzle diameter＞throat length＞throat diameter＞nozzle-to-throat clearance.The optimal parameter combination within the optimization range is determined as follows:nozzle diameter dj 3.3 mm,nozzle-to-throat clearance Lc 4.3 mm,throat diameter dt 4.7 mm and throat length Lk 25.76 mm.The simulation results and the experimental results are compared and analyzed,and the relative error is not more than 5%,which verifies the reliability and accuracy of the simulation model and the response surface model.
