Notes

The wind mill works on precept of converting kinetic strength of the wind into mechanical power.
The Kinetic Energy of any particle is equal to the half of its mass instances the rectangular of its speed, or ½ mv2.

K.E. =½* m*V2. ………………….. (1)

Where,
K.E.= kinetic energy
m= mass
V = velocity,

Mass flow rate (m) is depends upon the swept area of wind turbine, velocity of wind and density of wind. so,
Mass(m) = ?*A*V …………………. (2)

Here,
? = density of air (1.225 kg/m3)
A = area swept by rotating blade

Substituting equation (2) in equation (1) we get,

K.E. = ½ *?* A*V3 watts

Available wind power, Pa = (½ ? p D2 V3) /4
= 1/8 ? p d2 v3


for velocity 4.5m/s
pa = (½ ? p D2 V3)/4

for velocity 5.5m/s
pa = (½ ? p d2 v3)/4


for velocity 7.5m/s
pa = (½ ? p d2 v3)/4


for velocity 5.5m/s
pa = (½ ? p d2 v3)/4

Conclusion:
The VAWT is designed and fabricated in such a
way that the it could able to seize wind from all of the
route, strength developed from the venture is 32w
for a pace of 7.1m/s, the performance of vawt can
be improved via changing the size and shape of the
blade, the theoretical and experimental end result is
various because in theoretical calculation we
don't forget the wind is hitting all of the 8 turbine
blades, practically it isn't always.
our paintings and the consequences acquired are very
endorsed that vertical axis wind energy conversion
are conceivable and doubtlessly very make contributions to the
manufacturing of the smooth renewable power from
the wind even beneath low ideal sitting situations.
with the concept on dual carriageway, it will strength up road
lighting fixtures. in maximum cities, highways are a faster course for
each day trip and in need of constant mild makes
this a very green manner to provide natural electricity.
