本报告概述了一种估算太阳能中央接收器发电厂接收器总对流能量损失的方法。详细考虑了两种类型的接收器：圆柱形外置式接收器和腔式接收器。该方法旨在为设计人员提供一种估算总对流能量损失的工具，该工具基于当前从接收器到环境的对流热传递的知识，并可根据新信息进行调整。目前的知识包括来自最近两个大规模实验的信息，以及已经在文献中的信息。本文还概述了一种估算对流损失估算中不确定性的方法。总对流能量损失的样本估计和这些对流能量损失估计的不确定性包括在10mwe太阳能热中央接收厂（加州Barstow）的外部接收器和国际能源署小型太阳能发电系统项目（西班牙Almeria）的腔体接收器中。
This report outlines a method for estimating the total convective energy loss from a receiver of a solar central receiver power plant. Two types of receivers are considered in detail: a cylindrical, external-type receiver and a cavity-type receiver. The method is intended to provide the designer with a tool for estimating the total convective energy loss that is based on current knowledge of convective heat transfer from receivers to the environment and that is adaptable to new information as it becomes available. The current knowledge consists of information from two recent large-scale experiments, as well as information already in the literature. Also outlined is a method for estimating the uncertainty in the convective loss estimates. Sample estimations of the total convective energy loss and the uncertainties in those convective energy loss estimates for the external receiver of the 10 MWe Solar Thermal Central Receiver Plant (Barstow, California) and the cavity receiver of the International Energy Agency Small Solar Power Systems Project (Almeria, Spain) are included in the appendices.
