“…For a fully tracking collector or in cases where the angle of incidence is zero (normal incidence), the incidence angle modifier, K(θ) = 1 (Marif et al, 2014, Kalogirou, 2009. Even though full tracking or two-axis tracking parabolic trough systems are highly efficient since the angle of incidence is always zero, their use is limited by their greater mechanical complexity, less rigidity and more auxiliary piping requirements (Fernández-García et.al, 2010).…”

“…Regarding receiver thermal performance, several studies are available in literature on the thermal performance of parabolic trough receivers (Lüpfert et al, 2008,Burkholder and Kutscher, 2009, Burkholder and Kutscher, 2008, Ouagued et al, 2013, Li and Wang, 2006, Mokheimer et al, 2014, Yılmaz and Söylemez, 2014, Marif et al, 2014. Determination of heat flux distribution on the receiver is crucial to the analysis of the thermal performance of the system.…”

HIGHLIGHTS• Effect of optical errors on performance of a parabolic trough receiver is presented.• Actual heat flux profiles were obtained using Monte Carlo ray tracing and presented.• Thermal and thermodynamic analysis of the receiver is determined numerically.• Effect of optical errors on heat flux and temperature distribution is investigated.• Influence of optical errors on receiver entropy generation rates is presented. ABSTRACTThis paper presents results of an investigation covering the influence of optical errors on the thermal and thermodynamic performance of a solar parabolic trough system. The optical performance was evaluated by using Monte Carlo ray tracing for slope errors and specularity For the range of parameters considered, the intercept factor reduces by up to 21% while the overall thermal efficiency reduces by up to 17% as optical errors increase. Receiver thermodynamic performance is shown to deteriorate as slope errors increase.

Cameroon lives in the era of great infrastructures in order to reach the economic emergence by 2035. These infrastructures require a solid framework of energy provisions from many natural energy sources and resources that the country possesses. Speaking of natural energy resources, the country is particularly gifted by solar energy potential in the far north. This region of the land is densely populated but much of the populations do not have access to electricity since they live in remote areas far from national electricity grid. Solar thermal energy appears then as real potential to fulfill the growing demand of energy and reduce fossil fuel use dependence. Moreover, it would also be a grandiose opportunity for hospitals in these regions to provide hot water for Sterilization. As the design of a solar thermal plant strongly relies on the potential of direct solar irradiance and the performance of a solar parabolic trough collector (PTC) estimated under the local climate conditions, in this paper, we annually compute direct solar radiation based on monthly average Linke turbidity factor and various tracking modes in two chosen sites in the far north region of Cameroon. Also, a detailed two dimensional numerical heat transfer analysis of a PTC has been performed. The receiver has been divided into many control volumes along his length and each of them is a column consisting of glass, vacuum, absorber and fluid along which mass and energy balance have been applied. Direct solar irradiation, ambient temperature optical and thermal analyses of the collector receiver takes into consideration all modes of heat transfer and the nonlinear algebraic equations were solved simultaneously at each instant during a day of computation using En- 148gineering Equation Solver (EES). To validate the numerical results, the model was compared with experimental data obtained from Sandia National Laboratory (SNL). It has shown a great concordance with a maximum relative error value of 0.35% and thermal efficiency range of systems about 66.67% -73.2%. It has also been found that the one axis polar East-West and horizontal East-West tracking with 96% and 94% of full tracking mode respectively, were most suitable for a parabolic trough collector throughout the whole year in the two towns considered.
