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

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.
