摘要:
在合理假设的基础上,建立高层建筑受下垫面热辐射的物理数学模型.通过理论分析,得出高层建筑受下垫面热射辐射量的理论计算关系式.下垫面对高层建筑的热辐射随其距高层建筑水平距离的增加而迅速减少,存在一个有效的辐射范围,它仅与高层建筑的高度和半径有关.在该范围内对下垫面进行处理,可有效地减少或增加下垫面对高层建筑的热辐射.
Abstract:
The assumptions to the thermal radiation of the underlying surface agrees with Lambert cosine law,the tall building is equivalent firstly to a cylinder,then the mathematical model to describe the thermal radiation from the underlying surface to tall building is established and analyzed theoretically.The general formulas to calculate this thermal radiation are obtained.The formulas show that the rate of this thermal radiation decreases quickly with increasing the horizontal distance between the radiation surface and tall building,and there is a range of underlying surface from which the thermal radiation to the tall building is dominant; so taking some measures to this range,this thermal radiation can be effectively adjusted.
