Review of Experimental Approaches
for the Analysis of Aerodynamic
Performance of Vertical Axis Wind
Turbines
Vishal Kaushik and R. Naren Shankar
Abstract World of today is facing the problem of power crisis, because most of the
power generation units are running on the conventional resources which are depleting
day by day. Therefore, the need of alternative resources is the prime necessity of the
hour. Many experiments and studies have been conducted that highlights the benefits
of VAWT and its better performance over HAWTs. This paper presents a review
of various designs and performances delivered by different types of VAWTs. Major
designs that are in question in the presented paper are Savonius-type and Darrieustype vertical axis wind turbine. The paper aims at comparing various designs along
with their merits and demerits and parameters of various experimented VAWT. The
objective of this study is to derive an optimum design that can deliver the maximum
efficiency and power output within the given set of parameters like blade angle,
number of blades, aerofoil shapes, tip speed ratios, and wind velocity.

1 Introduction
With conventional resources of energy going toward extinction, there is a dire need
to move toward non-conventional energy resources. “Wind” energy is deemed to be
prime source to harvest energy. And modernized wind turbines can empower us to do
so. Optimizing the design parameters of wind turbines will lead us in achieving more
