Abstract

The invention provides an automatic optimization method for a turbomachinery blade, and the method comprises the following steps: performing parametric modeling on an initial blade profile by adopting an improved category shape transformation method, and flexibly constructing a suction surface molded line and a pressure surface molded line of the blade profile on the basis of applying fewer variables, so the method has the advantages of good robustness, few design parameters, high modeling precision and the like; employing a sample sampling method, an agent model and a cubic chaotic mapping whale optimization algorithm for automatically optimizing the blades, so the method has the advantages of high sampling efficiency, high agent precision, high optimization capacity and the like. By applying the automatic optimization method, the comprehensive performance of the impeller mechanical blade is improved.

Description

technical field [0001] The invention belongs to the technical field of turbomachinery optimization design, and relates to a method for optimizing a turbomachinery blade, in particular to an automatic optimization method for a turbomachinery blade, and is especially suitable for turbomachinery such as compressors, steam turbines, turbines, flue gas turbines, and expanders. Automatic optimization of blades. In the implementation of this method, firstly, the initial airfoil shape is parametrically modeled by using the improved category shape transformation method, and the suction surface and pressure surface shape lines of the airfoil are flexibly constructed on the basis of using less variables. Sampling method, surrogate model and cubic chaos map whale optimization algorithm are used to automatically optimize the blades. By using the above automatic optimization methods, the comprehensive performance of the blades is improved. Background technique [0002] Designing turbomac...
