The thermal performance of a single pass solar air heater with five fins attached was investigated experimentally. Longitudinal fins were used inferior the absorber plate to increase the heat exchange and render the flow fluid in the channel uniform. The effect of mass flow rate of air on the outlet temperature, the heat transfer in the thickness of the solar collector, and the thermal efficien...
Generational collectors are well known as a tool for shortening pause times incurred by garbage collection and for improving garbage collection efficiency. In this paper, we investigate how to best use generations with on-the-fly collectors. On-the-fly collectors run concurrently with the program threads and induce very short program pauses. Thus, the motivation for incorporating generations is...
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...
The realization of collector-up light-emitting complementary charge injection transistors is reported. The devices have been implemented in molecular-beam-epitaxy-grown n-InGaAs/ InAlAs/p-InGaAs and n-InGaAs/InP/p-InGaAs heterostructures using a self-aligned process for the collector stripe definition. Electrons, injected over the wide-gap heterostructure barrier (InAlAs or InP) by the real-spa...

This paper presents an optimization of a solar chimney power plant with an inclined collector roof using genetic algorithms. Five design parameters that affect the system performance are the collector radius, collector inlet height, collector outlet height, chimney height and diameter. A multi-objective design to simultaneously optimize three conflicting objectives including system efficiency, ...
Energy is one of the essential requirements of livinghood. In present scenario conventional energy resources for producing energy to sustain our lives has become a necessity. Since these sources are depleting at faster rate and cost of energy is increasing simultaneously, so conversion of renewable form of energy is much desired and solar energy is a good resource. The present work is based on ...
