摘要

作者自行设计了大尺寸吸气式篦齿换热风洞实验台并通过它对篦齿腔中的内部流场进行了详细的研究

得出了篦齿腔中速度场和压力场及流场内部旋涡分布规律。同时测量了在不同雷诺数、齿顶厚和齿隙比工况下

篦齿腔内二维流动状况及旋涡分布

分析得出不同雷诺数和齿隙比对篦齿腔内部流场的影响。并且测量了篦齿顶板表面的温度和换热系数的分布

得出雷诺数和齿顶厚与齿隙比对篦齿顶板局部换热规律的影响

Abstract

We built a big scale inhale labyrinth heat transfer wind tunnel.Detailed experimental investigation on the flow field in the labyrinth cavity reveals the two dimensional velocity and pressure fields as well as vortix distribution in the flow field and local heat transfer coefficient distribution on the roof of labyrinths.Therefrom the influences of different Reynolds number and T/C on the velocity and pressure distributions in the cavity of the labyrinth and on the heat transfer coefficient of the labyrinth roof seal are found out.
