Abstract
Situations such as low wind speed, high turbulence and frequent wind-direction change can reduce the
performance of horizontal axis wind turbine (HAWT). Certain vertical axis wind turbine (VAWT) designs have the
ability to operate well in these harsh operating conditions but they possess low power coefficient generally. In order
to tackle the mentioned problems, a novel cross-axis-wind-turbine (CAWT) is conceptualized to extract wind energy
from both the horizontal and vertical directions of the on-coming winds to maximize the wind energy generation. The
CAWT consists of three vertical blades and six horizontal blades arranged in cross axis orientation. Initial testing
showed that maximum RPM generated by the CAWT is 166% higher than the VAWT under the same experimental
conditions with well-improved starting behavior. Computational Fluid Dynamics (CFD) analysis was done to
illustrate the flow field of the deflected and channeled air stream by omni-directional shroud. The air stream deflected
upwards by the guide vane interacts with the horizontal blades. The CAWT is applicable in a wide variety of
locations, creating significant opportunities for the use of wind energy devices and therefore alleviating dependencies
on fossil fuel.

1. Introduction
A wind turbine is a device that converts energy from the wind into electrical power. There are
basically two types of wind turbine; the horizontal axis wind turbine (HAWT) and the vertical axis wind
