一、前言本文将轴流风机中的最佳通流状态、最佳反作用度的概念,对子午加速风机作了引伸。并导出:Ω_(∞dk)=(1/2)·{1+(3/2)·(△u/△v_u)/(1-△u/△v_u)}为子午加速风机的动翼最佳理论扩压度。
I. INTRODUCTION In this paper, the concept of optimum flow condition and optimum reaction degree in axial flow fan is an extension of meridian acceleration fan. (∞dk) = (1/2) · {1+ (3/2) · (△ u / △ v_u) / (1- △ u / △ v_u)} Good theoretical degree of expansion.
