摘要
通过实验测试 ,研究了空气自然对流状态下横圆管被稳态加热时管壁温度圆周方向温度变化率 .热管壁与周围冷空气圆周方向自然对流换热强度决定了管壁温度圆周方向温度变化率 .文章揭示管壁温度圆周方向温度变化率的同时 。
The paper has studied the surface temperature variety rate along the circumference of a horizontal circular cylinder in natural convection station by experiment. The intensity of natural convection heat transfer between the hot surface and the cold air around the cylinder decides the circumferential temperature variety rate . The heat transfer by natural convection including heat conduction and heat convection is a complex and abstract course. Here it has analyzed and described when the circumferential temperature variety rate was discovered.
