Natural Convection Heat Transfer from an External Receiver

摘要

A numerical solution of turbulent, two-dimensional, natural convection heat transfer for a high temperature, vertical surface is presented in this work. This is relevant to heat transfer from the receiver of a solar central receiver power plant on a calm day (no wind). It is the lower bound of convective loss from an external receiver. Application of wall suction to the receiver surface is also examined as a means of reducing convective loss. In the Appendix an analysis of the economic impact of energy loss from a receiver is presented. It demonstrates the importance of receiver performance with regard to solar central receiver plant cost. (ERA citation 05:008301)
