基于代理模型外混式空气雾化喷嘴雾化性能优化研究
Optimization study on atomization performance of external-mix air-atomizing nozzle based on surrogate model
摘要
Abstract
To investigate the influence of operating parameters on the atomization performance of external-mix air-atomizing nozzles and determine the optimal operating parameters for achieving the best atomization effect,a combined method of finite element model construction and optimization calculation was adopted for relevant research.Using gas inlet pressure,liquid inlet pressure,and liquid kinematic viscosity as optimization variables,and atomization cone angle and outlet flow coefficient as optimization objectives,an orthogonal experiment was designed and conducted.Based on the orthogonal experimental data,a response surface surrogate model was established,and this surrogate model was optimized using genetic algorithm,followed by simulation verification and comparative analysis of results.The results show that gas inlet pressure,liquid inlet pressure,and liquid kinematic viscosity all have significant effects on nozzle atomization performance;when the gas inlet pressure is 0.057 2 MPa,liquid inlet pressure is 0.111 2 MPa,and liquid kinematic viscosity is 0.057 3 Pa·s,the nozzle atomization performance reaches its optimum.Compared with the original model,the atomization cone angle increases by 34.62%,and the outlet flow coefficient improves by 49.36%.The research can provide references for the setting of operating parameters for nozzles.关键词
