Optimal forecasting of thermal conductivity and storage in parabolic trough collector using phase change materials

Experimental investigations on the performance of a collector¬タモstorage wall system using phase change materials

Experiments have been performed on the thermal behavior of a collector–storage wall system using PCM (phase change material). PCM slabs were attached on the gap-side wall surface to increase the heat storage. The test was carried out for a whole day with charging period of 6.5 h and discharging period of 17.5 h, respectively. Wall and air temperatures as well as air velocity in the gap were mea...

Thermal Management Using “ Dry ” Phase Change Materials

The thermal response characteristic of a hybrid cooler that is charged with a “dry” solid-solid phase change compound is evaluated. A mathematical model that simulates the performance of a cooler/heat storage unit is formulated. A prototype heat sink that incorporates heat storage using a “dry” PCM is tested, and used to benchmark the simulation model. Different heating and cooling strategies a...

Ray-Thermal-Structural Coupled Analysis of Parabolic Trough Solar Collector System

An effective approach to sustainable energy is the utilization of solar energy. The parabolic trough collector with central receiver is one of the most suitable systems for solar power generation. A type of concentrating solar collector that uses U-shaped troughs to concentrate sunlight onto a receiver tube, containing a working fluid such as water or oil, which is positioned along the focal li...

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...
