Introduction
The use of wind power has a very long history. Some historians contend
that wind turbines, sometimes known as windmills, were known much before
the year 3000. They also claim that stone windmill ruins were found in
Egypt close to Alexandria. Yet, historical records indicate that
windmills were initially used around 640 AD along the Persian-Afghan
border.
A rotating machine which
converts the kinetic energy in wind into mechanical energy is a wind
turbine. Environmental concerns such as climate change and other factors
has increased the worldwide interest in renewable energy systems like
wind turbines. Wind energy may be captured using both horizontal and
vertical axis wind turbines and is a significant source of renewable
energy. The fluid flow through the wind turbine is specifically
predicted using numerical simulations that make use of computational
fluid dynamics and look at a number of blade shapes. Reports on air blow
simulations through turbine rotors that evaluate the device’s
performance characteristics. A dimensional form of the power output of
the wind turbine is expressed in the computational fluid dynamics
software as a function of the wind free stream velocity and rotor
rotational speed. Air flow through the turbine rotor which asses the
performance of the device. A dimensionless form of the power output of
the wind turbine is expressed in the computational fluid dynamics
software as a function of the wind free stream velocity and rotor
rotational speed. Explore the transient effects caused by flow
interaction between the stationary components and the revolving blades,
a sliding mesh model is used.
