【摘要】 采用旋转的实验方法,测试显示了热圆管与冷空气自然对流状态下横圆管外壁温度的圆周方向分布规律.得出在不同管壁温度区域,管壁温度具有不同的圆周方向分布规律的结论.管壁温度在较低区域内,管壁温度由底部到顶部递增分布;管壁温度在较高区域内,管壁温度由底部到顶部递减分布.更多还原

【Abstract】 Applying a rotation experiment method, the distribution regulations of the surface temperatures along circumference of a horizontal circular cylinder in natural convection between the hot surface and the cold air are displayed the experiment shows that in different surface temperature district the circumferential surface temperatures have different distribution regulations. In lower surface temperature district, the surface temperature increases from bottom to top, however, in higher surface temperature distrct, the surface temperature decreases from bottom to top.更多还原
