摘要
采用响应曲面法和数值模拟方法,以涡旋管分离器结构参数为设计变量,以分离效率和压降为目标函数,对涡旋管结构进行四因素的优化设计分析.结果表明:叶片数量对压降和分离效率影响较小;旋转角度对压降影响较弱,但对分离效率影响显著,且旋转角度与螺距及中心轴轴径对分离器分离性能的交互作用明显;螺距和中心轴轴径对压降和分离效率影响较大,且两者对分离器压降的影响有着很强的交互作用;与初始模型相比,基于响应曲面法设计的优化模型性能较佳.
Abstract
By response surface methodology and means of numerical simulation,the four-factor optimization design analysis was performed with the structural parameters of the vortex tube separator being the design variable and the total pressure drop and the separation efficiency as the objective functions.The results show that the number of vanes has little effect on the pressure drop and the separation efficiency.The blade rotation angle has a weak effect on the pressure drop,but imposes a significant effect on the separation efficiency,and the interactions between the blade rotation angle and the blade pitch,and between the blade rotation angle and the shaft diameter on the separation performance are obvious.The blade pitch and shaft diameter have a great influence over the pressure drop and separation efficiency,and the two have a strong interaction on the pressure drop.Compared with the initial model,the performance of the optimized model based on the response surface is better.
