Nanofluid-based direct absorption solar collector
Tập 2 Số 3 - 2010
Solar 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 that
mixing...
Experimental study of the horizontally averaged flow structure in a model wind-turbine array boundary layer
Tập 2 Số 1 - 2010
When 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
performed. The b...
Wake structure in actuator disk models of wind turbines in yaw under uniform inflow conditions
Tập 8 Số 4 - 2016
Reducing 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
yawed cond...
Statistical analysis of kinetic energy entrainment in a model wind turbine array boundary layer
Tập 4 Số 6 - 2012
For 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
spectral dec...
A novel methodology for simulating maximum power point trackers using mine blast optimization and teaching learning based optimization algorithms for partially shaded photovoltaic system
Tập 8 Số 2 - 2016
When 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 at GMPP...
Power enhancement of partially shaded PV arrays through shade dispersion using magic square configuration
Tập 8 Số 6 - 2016
This 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
effect over t...
Numerical study on coupling effects among multiple Savonius turbines
Tập 4 Số 5 - 2012
A 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
optimization of...
Wind power potential assessment for seven buoys data collection stations in Aegean Sea using Weibull distribution function
Tập 4 Số 1 - 2012
This 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,
maximum ene...
Photovoltaic power generation and its economic and environmental future in Bangladesh
Tập 7 Số 1 - 2015
Bangladesh 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
technologies...
Nusselt number and friction factor correlations for solar air heater duct with broken V-down ribs combined with staggered rib roughness
Tập 4 Số 3 - 2012
Artificial roughening of a broad wall of solar air heater leads to significant
enhancement in heat transfer besides comparable rise in friction losses. This
paper presents the outcome of experimental study on heat transfer and fluid
friction characteristics of solar air heater duct roughened with broken V-down
rib combined with staggered rib piece. Experimental data were collected on a
high aspect...
