Structural Optimization of Vortex Tube Separator Based on Response Surface Methodology
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.
