Nanofluid-based direct absorption solar collectorSolar energy is one of the best sources of renewable energy with minimal environmental impact. Direct absorption solar collectors have been proposed for a variety of applications such as water heating; however the efficiency of these collectors is limited by the absorption properties of the working fluid, which is very poor for typical fluids used in solar collectors. It has been shown tha... ...

Experimental study of the horizontally averaged flow structure in a model wind-turbine array boundary layerWhen wind turbines are deployed in large arrays, their ability to extract kinetic energy from the flow decreases due to complex interactions among them, the terrain topography and the atmospheric boundary layer. In order to improve the understanding of the vertical transport of momentum and kinetic energy across a boundary layer flow with wind turbines, a wind-tunnel experiment is performe... ...

Wake structure in actuator disk models of wind turbines in yaw under uniform inflow conditionsReducing wake losses in wind farms by deflecting the wakes through turbine yawing has been shown to be a feasible wind farm controls approach. Nonetheless, the effectiveness of yawing depends not only on the degree of wake deflection but also on the resulting shape of the wake. In this work, the deflection and morphology of wakes behind a porous disk model of a wind turbine operating in ya... ...

Statistical analysis of kinetic energy entrainment in a model wind turbine array boundary layerFor large wind farms, kinetic energy must be entrained from the flow above the wind turbines to replenish wakes and enable power extraction in the array. Various statistical features of turbulence causing vertical entrainment of mean-flow kinetic energy are studied using hot-wire velocimetry data taken in a model wind farm in a scaled wind tunnel experiment. Conditional statistics and spec... ...

A novel methodology for simulating maximum power point trackers using mine blast optimization and teaching learning based optimization algorithms for partially shaded photovoltaic systemWhen the photovoltaic (PV) system is fully illuminated, the voltage-power characteristic of the array has one maximum power point (MPP). This point can be tracked by conventional maximum power point tracker algorithms. On the other hand, in partially shaded PV, the voltage--power characteristic has only one global MPP (GMPP) and multiple local MPPs. It is important to operate the PV system... ...

Power enhancement of partially shaded PV arrays through shade dispersion using magic square configurationThis paper proposes a new static reconfiguration technique to configure the modules in the Photo-Voltaic (PV) array so as to enhance the generated power from the array under partial shading conditions. In this approach, the physical location of the modules in a Total Cross Tied (TCT) connected PV array is arranged based on the Magic Square (MS) pattern so as to distribute the shading effec... ...

Numerical study on coupling effects among multiple Savonius turbinesA Savonius rotor can be used as a wind or water current energy conversion device that produces electricity. In spite of their simple structure and assembly, Savonius turbines have less commercial appeal than other types of turbines due to their relatively low energy conversion efficiency. In order to increase the output power of a Savonius turbine, most studies have only focused on optimiz... ...

Wind power potential assessment for seven buoys data collection stations in Aegean Sea using Weibull distribution functionThis paper utilizes three hourly measured values of wind speed and direction from seven buoys data collection stations in Aegean Sea to study the wind speed and power characteristics applying the Weibull shape and scale parameters. Specifically, the site dependent, annual and monthly mean patterns of mean wind speed, Weibull parameters, frequency distribution, most probable wind speed, max... ...

Photovoltaic power generation and its economic and environmental future in BangladeshBangladesh is facing an energy crisis that is likely to become worse in the future because of insufficient power generation. Approximately 50% of the total population lives without grid-connected electricity. Moreover, the people connected to the grid are unable to access an even and continuous power supply on a daily basis. This research investigated the potential of renewable energy tech... ...
