Abstract


Detailed simulations in aim to evaluated performances of a solar parabolic trough collector under climatic conditions of Cameroon Sahelian Zones was devoted by using a computer program based on one-dimensional flow implicit finite volume method with energy balance. The heat collecting element of the collector was divided into several control volume and heat balance correlations was applied for each control volume of the trough. In other to solve the three linear algebraic equations obtained from the model, the Tri-Diagonal Matrix Algorithm was implemented. At all, the model estimates for a typical day of the least sunny and the sunniest months, the optical and thermal performances of the collector, the solar energy absorbed the useful thermal heat and the heat lost to the ambient. The E-W horizontal traking mode which is getting closer with full tracking mode is assumed to collect high optical efficiency at about 74% during all the seasons. The maximum of outlet temperature of heat transfer fluid obtained at the right end of the absorber tube is about 140°C, 138°C and 80°C during a typical day of the least sunny months and 180°C, 180°C and 90°C during a typical day of the sunniest month respectively for water, air and TherminolVP-1TM synthetic oil used as heat transfer fluid. Outlet temperatures obtained from the model compared with data from Sandia experimental tested collector and from another devoted work show that the model is very suitable to predict the behavior of a solar parabolic trough collector under climatic conditions of Cameroon Sahelian Zones.
