Numerical simulation of thermal losses on the parabolic trough collector under TRANSYS

摘要

The use of parabolic trough collectors PTC in power production of electricity increases more and the costs of facilities decreases and becomes competitive. Studies of this technology are interested in improving performance. This last factor is very impressive in the design of facilities. In this objective, we are interested in the modeling and simulation of heat losses by a model of PTC based on measurements performed by Sandia Laboratories (USA). In the practical case, the vacuum in the annular space between the absorber tube and glass envelope, the results obtained by the model are satisfactory.
