The high emission of fossil fuels are major driving forces in renewable energy technology
development. In response, the lift-type vertical axis wind turbines (VAWT) is experiencing a …

With the main advantages of simple shape, smart structural and wind direction
independence, Straight-bladed vertical axis wind turbines has been increasingly used in …

A comparative analysis of seven commonly-used eddy-viscosity turbulence models for CFD
simulations of VAWTs is presented. The models include one-to four-equations, namely the …

Abstract Straight-bladed Vertical Axis Wind Turbines (SB-VAWTs) have recently attracted
much attention as they are considered to be an option for wind energy utilization, whether in …

The current study systematically analyzes the impact of solidity (σ) and number of blades (n)
on the aerodynamic performance of 2-, 3-and 4-bladed Darrieus H-type vertical axis wind …

Vertical axis wind turbines (VAWTs) have received growing interest for off-shore application
and in the urban environments mainly due to their omni-directional capability, scalability …

Urban wind energy can provide a decentralized local source of energy for residential areas
and reduce the cost of energy by avoiding the losses/costs of long-distance energy …

The flow performance of vertical-axis wind turbines (VAWTs) is significantly deteriorated by
dynamic stall at low tip-speed-ratios (TSR). Dynamic stall occurs periodically during the …

This study presents experimental and numerical investigation for the effect of number of
blade (solidity) on the power and thrust coefficients of a small-scale horizontal-axis wind …

In an urban environment, dual vertical axis wind turbines (VAWTs) are expected to
demonstrate more advantage than horizontal axis wind turbine. For VAWT, solidity is one of …
