Structural Optimization of Double Swirler Based on Experimental Design

Abstract

Based on several structure optimization parameters for the description of the geometric features of a double oblique radial swirler, simplified structure design parameters and value interval were determined. And, the CFD analysis model of the swirler is established. Based on the approaches of multi-wheel space filling experimental designs, 17 design schemes were gained, then CFD numberical experiments on the cold single-phase flow field was developed to all design schemes. Finally, the optimal design scheme were found by numberical space filling experimental design method in a several turn.
