Optimal design of the solar tracking system of parabolic trough concentrating collectors

Improvements in efficiency of solar parabolic trough

Solar energy is primary source of all type of energy which is present in nature i.e. all the energy derived from it. So, direct utilization of solar energy into useful energy is important. There are so many solar thermal equipments in which concentrating type collector heated the fluid up to 100 to 400C. It is employed for a variety of applications such as power generation, industrial steam gen...

Numerical analysis of performance of solar parabolic trough collector with Cu-Water nanofluid

In the present work the effect of Cu-Water nanofluid, as heat transfer fluid, on the performance of a parabolic solar collector was studied numerically. The temperature field, thermal efficiency, mean-outlet temperatures have been evaluated and compared for the conventional parabolic collectors and nanofluid based collectors. Further, the effect of various parameters such as fluid velocity, vol...

Geometric Optimization of Concentrating Solar Collectors using Monte Carlo Simulation

This paper presents an optimization algorithm for designing linear concentrating solar collectors using stochastic programming. A Monte Carlo technique is used to quantify the performance of the collector design in terms of an objective function, which is then minimized using a modified Kiefer-Wolfowitz algorithm that uses sample size and step size controls. This process is more efficient than ...
