The Wind energy is more reliable and speedier growing, among the renewable energy resources, due to the world environment challenges as well as increasing demand for energy. The wind turbine system's stability is cumbersome due to the uneven distribution of wind. Centrifugal and gravitational...

An evolutionary computation approach for optimization of power factor and power output of wind turbines is discussed. Data-mining algorithms capture the relationships among the power output, power factor, and controllable and non-controllable variables of a 1.5MW wind turbine. An evolutionary...

A laboratory scale flexible rubber blade water wheel has been investigated at the hydraulic laboratory of University of Southampton. The effect of channel width on water wheel performance has been studied. Different upstream and downstream channel widths are set for the tests. In this paper, the...

There is a great potential for solar power utilization in the Eastern part of Saudi Arabia by employing solar photovoltaic (PV) modules. Dust accumulation on the surface of solar PV modules, mirrors, reflectors and other solar collectors is of great concern due to occasional to frequent dust...

Based on an unperturbed airflow assumption and using a set of validated modelling methods, a series of activities were carried out to optimise an aerodynamic design of a small wind turbine for a built up area, where wind is significantly weaker and more turbulent than those open sites preferable...

Driven by the need to verify a CFD model of a novel vertical axis wind turbine (VAWT) device, a 1.6m diameter prototype was designed, built to a high specification and tolerance and then tested in the industry standard MIRA wind tunnel over the full wind range that might be expected in an urban...

Numerical simulations have been carried out on the solar chimney power plant systems coupled with turbine. The whole system has been divided into three regions: the collector, the chimney and the turbine, and the mathematical models of heat transfer and flow have been set up for these regions....

A pilot experimental solar chimney thermal power generating equipment was set up in China. A simulation study was carried out to investigate the performance of the power generating system based on a developed mathematical model. The simulated power outputs in steady state were obtained for...

A Kalina cycle with ejector (EKalina cycle) is proposed in this paper. In the EKalina cycle, an ejector is used to substitute for the throttle valve and the absorber in the Kalina cycle system 11 (KCS 11). The exhaust pressure of the expander is decreased by the ejector resulted in an increase...

In this paper, a performance analysis based on the power output, thermal efficiency, maximum power output (MP) and maximum thermal efficiency (MEF) criteria have been carried out for an air-standard irreversible Dual–Miller cycle (DMC) with late inlet valve closing (LIVC) version which covers...
