摘要
用实验测量了不同风速、风向下的温差和热流数据,给出了从实测温差和热流中提取表面换热系数的辨识方法,分析了风速、风向对墙体表面换热系数的影响,并最终得到了墙体表面换热系数随风速、风向变化的关系式。
This article uses experiments to measure the data of temperature differences and the heat streams under the condition of different wind speed and direction; put forward the explanatory means of distilling the wall body surface heat exchange coefficient from the experimental measuring of temperature differences and heat streams; then analyzes the infection of the wind speed and direction to the wall body surface heat exchange coefficient;and at last it gets the equation on that the wind speed and direction change, and the wall body surface heat exchange coefficient varies with the changes of wind speed and direction.
