摘要

建立了某实用的后缘切角波瓣混合器流场数值计算模型

通过三维数值模拟研究

得到了波瓣后缘切角的角度值对于波瓣混合器流场热混合效率和总压恢复系数的影响规律.结果表明:后缘切角在2.5°至15°之间变化时

热混合效率随切角角度的增大而增大

总压恢复系数随切角角度的增大而减小;后缘切角在15°至60°之间变化时

热混合效率随切角角度的增大而减小

总压恢复系数随切角角度的增大而增大.

Abstract

The principle of effect of different cut angles at trailing edge of a practical lobed mixer on the thermal efficiency and the total-pressure recovery coefficient was studied by 3D-CFD(computational fluid dynamics)numerical simulation.The results show that

when the angles cut at trailing edge of the lobed mixer vary from 2.5° to 15°

the thermal efficiency augments and the total-pressure recovery coefficient decline as the angle increases

and when the cut angles vary from 15° to 60°

the thermal efficiency declines and the total-pressure recovery coefficient augments as the angle increases.
