矿井风硐S弯段压力损失的研究

RESEARCH OF THE HEAD OF AIR CURRENT THROUGH A CURVY AIRCOURSE IN THE SHAPE OF S

本文分析矿井风硐S弯流场压力损失的机制，建立了以幂函数表示的圆形裁面S弯局阻系数计算模型．通过实验确定模型中的各项系数，并检验模型的正确性．

In this paper, the mechanism of air head variation is analysed in curvy aircourses in the shapeof S of wind tunnel in mine. A power law mathematical model of air shock resistance factor has been madeup for the S-like curvy airway with circular transverse section. By expetiment, factors in the model weredetermined and the rationality and notability of the model and its variables were tested.
