| 摘 要： | 对滚动轮胎表面同时考虑风吹和旋转的影响,在风洞中采用热质比拟原理,对风吹旋转圆盘的对流换热规律进行了研究,得到了圆盘半径范围内局部点的无量纲因次方程式.用相似原理把对流换热实验结果模拟到轮胎上,确定了在行驶速度为60~90 km/h的范围内,165/70R10型轮胎的平均对流换热系数随速度的变化规律,得到了拟合公式.研究表明平均对流换热系数随着速度的增加呈现线性增加的趋势.

| Abstract: | Rotating disk immersing a gaseous free stream flow was experimentally investigated by using heat and mass transfer analogy principle and dimensionless equation at the range of radius of disk was concluded.The rule of convective heat transfer of disk was transformed to tire of 165/70R10 by using similarity principle,and the dependence of convective heat transfer coefficient of the specific tire on velocity was confirmed within the range of velocity from 60 km/h to 90 km/h.It is from the relation showed that the convective heat transfered coefficient of tire linear increasesd with an increase of the velocity. |
