Abstract:

The phenomenon of photovoltaic systems is based on the principals of semiconductor physics and they operate with a semiconductor element, such as silicon. Photovoltaic cells can generate electricity only when they receive a certain amount of photon energy and thus they convert only a fraction of the solar irradiance, which is received from the sun in the form of electromagnetic radiation in the electromagnetic spectrum, into electrical energy. The remaining radiation is stored as heat in photovoltaic systems, causing some irreversibilities in the system. In general, the experimental setup, the

Abstract:

Abstract In the family of heat engines, the gas turbine is unique in that it is used to produce two different kinds of useful power. By converting combusted fuel heat into work, a gas turbine engine can produce external shaft power (e.g., to drive a connected electric generator) or jet power (e.g., as a jet engine, to produce thrust forces to propel an aircraft). This means that the gas turbine’s thermodynamic figure of merit, thermal efficiency, is multifaceted, and calls for a nuanced examination.

Energy losses of flowing air through solar air heater (SAH) duct does not consider in the ther-mal performance. Therefore, thermohydraulic performance based on exergetic efficiencies is a tool to assess the performance by considering energy losses in propelling the air simul-taneously to identify the best ribs configuration. This paper presents the thermohydraulic performance of SAHs exploiting various ribs roughness’s. The performance of SAHs is based exergetic evaluation based on IInd law of efficiency is most suitable for design of artificial-ly roughened SAH as it includes both requirement

Abstract:

The research presents the daily and monthly global solar radiation on a horizontal surface in Iraq and applies it to the PVT water system. The research contributes in two ways: first, it models a novel copper pipe system that improves thermal efficiency in an actual environment, and second, it investigates the hourly and daily intensity of solar radiation in Iraq using collected irradiation at mass flow rates ranging from 0.01 to 0.02 kg per second, the surface temp of the PVT model was calculated. The surface temp was also computed using the experimental data in the PVT model. The findings we

Abstract:

In this study, the effect of different concentration of the Aluminium oxide-based nanofluid on the performance of Solar Desalination system was discussed. The Aluminium Oxide was used in different concentrations 1%, 2% and 6% on weight basis. The flow rate was also varied and its effect on the system efficiency was discussed. The nanofluid was compared with the water and there was improvement occurred in the efficiency during variation of incident radiation. With an increase in the concentration of Aluminium oxide nanoparticles, improvement in the efficiency was attained. More efficiency was a

Abstract:

This study illustrates a factory’s production efficiency by demonstrating its energy efficiency in the dairy milk industry. Determining the thermal energy to save energy enhances the prof-itability of the factory. The aim of this study is to conduct a thermal energy and production analysis of a dairy milk factory based on annual production. This study intends to make the conclusions more realistic by using production and energy data dependability analysis. The overall power consumption for the thermal and electric energy processes was found to be as 180,520 [W]. The target-specific energy cons

Abstract:

Gas industry as one of the greatest sectors of energy, has a major role in environmental issues. A category of energy intensive parts in gas industry is heaters in City Gate Stations which consume colossal volumes of the purified gases. Different optimization strategies to improve the efficiency of these heaters entailing preheating, waste heat recovery of exhausts, insulating pipelines and mounting economizers or recuperators or even using renewable energy sources have been already introduced. Besides, finding the optimized geometry is very essential in improving the efficiency. In this study
