Spiral groove pipe optimization method

Abstract

The invention discloses a spiral grooved tube optimization method, and belongs to the field of spiral grooved tube heat exchange optimization. Through overall optimization of the shape of the spiral groove, the optimized spiral groove pipe with the performance improved greatly can be obtained, specifically, parameterized description is conducted on the spiral groove molded line through the spline curve, the molded line more sensitive to coordinate changes of the control points can be obtained, and then the requirement for fine adjustment and optimization of the molded line is met. According to the method, the genetic algorithm is adopted to screen the optimal spiral groove profile in the optimization target value, so that the coordinates corresponding to the screened spiral groove profile can be selected, crossed and / or mutated to obtain the optimized spiral groove profile, and the optimized spiral groove profile can be iteratively calculated again to obtain the optimization target so that a more excellent spiral groove tube type line can be obtained; and meanwhile, the performance parameters of each generation of population are predicted through the agent model, a large number of CFD calculation processes are replaced, calculation resources are saved, the optimization period is shortened, and the efficiency of the optimization process is improved.
