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...

2 00 7 A closed parabolic trough solar collector

Parabolic trough[1] is the most mature technology for large scale exploitation of solar energy. Several power plants based on this technology have been operational for years, and more are being built. However, the current technology suffers from a too high installation cost. This high cost makes it very hard to compete economically with fossil energy without government subsidies, compromising t...

Videotheodolite Measurement Systems – State of the Art

Engineering geodesy has undergone significant changes in recent years. Most obvious is the transition from analog to digital operating modes. Automation of surveying instruments is indeed in high demand. The automation in the area of tacheometer measurement systems has began years ago with automatic target recognition (ATR) and tracking features. Image processing has become a powerful tool of s...

Experimental Investigation on the Effect of Partially Metal Foam inside the Absorber of Parabolic Trough Solar Collector

In the present work the efficiency of a solar parabolic trough has been investigated experimentality. parabolic trough solar collector constitute a proven source of thermal energy for industrial process heat and power genaration. The impact of  using the partially porous media in the absorber on the efficiency of PTC (parabolic trough collector) has been investigated. The porosity of copper foa...
