ABSTRACT

India being a developing country has high population and large number of vehicles which has resulted into increase air pollution over the periods of decades. In India, the implementation of electric vehicle is must necessary to overcome the effect of pollution on environment which is increasing day by day rapidly with increasing the number of conventional I.C. engine vehicle. In electric vehicle, the requirement of charge the battery after travel particular distance is major issue.

So, distance covered by single charged battery is limited because of weight, capacity, cost & space where it fixed are affecting parameters which doesn’t allow to increase the battery capacity above certain limitations. Without increasing the battery capacity, our idea is to generate electricity in electric vehicle by rotating wind turbine which is mounted on vehicle while vehicle in motion.

Basically, this idea may decrease the recharging required of electric vehicle’s battery & gives more range in single charge.

Chapter 1: Introduction

Problem Definition

Air pollution in India is quite serious issue with the major sources being fuelwood and biomass burning, fuel adulteration, vehicle emission & traffic issues. That traditional fuel options are emitting pollution by using the conventional vehicle.

The trend of automobile vehicle is moving on electric vehicle which is not emitting mobile pollution as compared to conventional vehicle. But, the electricity required to charge the battery is further produced by burning the coal in power station.

According to, trandingeconomics.com electricity production from coal sources (% of total) in India was reported at 75.08% in 2014, according to the world bank collection of development indicators, compiled from officially recognized sources.

As increases demand of electricity for charge the vehicle’s battery, electricity generation by power plant through burning of coal is also increases which will lead also pollution issue in nearly future.

So, only depending on electricity generated by power plant we will go in the direction of generating electricity as renewable energy source.

Overview of The Product

Main aim of the project is to design a wind turbine assembly which generates electricity.

Wind turbine rotates when vehicle is in motion, the impacting wind velocity helps to rotates the wind turbine.

That generated electricity either used to run accessories or charge the battery.

Renewable wind energy source utilized to generates the electricity which helps to improve the vehicle’s range.

Objective of Project

We will try to produce efficient electricity at particular wind velocity.

Objective of our project will be to concentrate on range of electric vehicle.

Our whole assembly should be light weight so extra weight doesn’t affect the vehicle’s dynamics.

Design of blades will be properly designed for starting rotation at minimum velocity.

Chapter 3: Introduction To Project

3.1 Wind Energy

Wind energy which is the one of the most important sources of renewable energy which easily available in nature.

At the end of this decades, most of the countries are moving towards to implement more and more wind turbine around the world, because of the increasing need of electricity without any type of pollution.

Wind energy is also known as green energy because it doesn’t produce any type of pollution.

Estimated that roughly 10 million MW of energy are continuously available in earth’s wind.

According to statistics the electricity consumption is increasing largely due to the introduction of more electric vehicle.

According to CEA (Central Electricity Authority) in India 160 GW power is consumed in 2016-17.

Around 10% of it only is produced by wind, which is the installed capacity, during the year 2016-17 about 46,011 million kWh generated, which is the 3% of overall generation.

Wind Turbine

The commercial wind turbine is not suitable for small scale application as it requires more area, and cost of installation is large.

Modern society is moving towards electric vehicles, so there needs an advanced technology of power production, here the concept of small portable wind turbine which can easily connected to electric vehicles.

So, total consumption of electric power for electric vehicle is reduced.

For example, a fast-moving electric locomotive such as train or long distance heavy and passenger vehicle that travels in good speed produce enough energy as a source for wind turbine and a moving locomotives to produce electric energy.

Concepts such as the selection of suitable turbine parameters, generator performance in order to improve the energy yield from the induced wind and vehicle application as the location and the design.

Wind turbines are manufactured in different sizes and powers. Wind turbines are divided into 2 classes: small 200m2 or less, and large wind turbines, with a rotor-swept area larger than 200m2.

Two types of axes are important in micro wind turbines: Vertical Axis micro Wind Turbines (VAWT) and Horizontal Axis micro Wind Turbines (HAWT).

However, the efficiency of a VAWT is lower than HAWT because the blades of a HAWT are perpendicular, and the rotation axis is parallel to the direction of wind.

Selection of efficient blades for model is important for better efficiency and output. The blades should have less weight, high lift force , and better capture of kinetic energy of wind.

Aerofoil, forward straight and backward curve blade can be used in the turbine.

Theoretical Calculations

Wind Turbine Performance:

An amount of wind mass m and density ? that flows with speed u in the axial direction of the wind have kinetic energy. Mechanical power Pw is derivative of kinetic energy with the time,

(3.1)

Cp is the power co-efficient which is the result of electrical power (output power) Pout over the mechanical power (input power) Pin,

(3.2)

Wind Turbine Analysis:

In the nozzle, there is outlet velocity and inlet velocity. The inlet velocity is the air when it is entering the nozzle. It will be less than the outlet velocity which is the air when it is going out of the nozzle directing to the blades of the fan. This will achieve the purpose of the convergent nozzle so the velocity will be increased at the outlet point and give more forces to the blades to rotate. for the required data for calculation, see equation (3.3) for relationships between temperature and the velocity, equation (3.4) for the Mach number formula, (3.5) for the ratio of the stagnation temperature and static temperature, and (3.6) for the ratio of inlet to exit area.

(3.3)

where T01 is the stagnation temperature, Cp is the specific heat, T1 is the static temperature, and C1 is the inlet velocity.

(3.4)

where, is the speed of the sound, and k is the ideal gas constant (for air k = 1.4)

(3.5)

(3.6)

in equations (3.7),(3.8),(3.9), and (3.10) are required to determine the outlet density which is contributed on the wind power equation,

(3.7)

(3.8)

(3.9)

Mechanics of the Wind Turbine:

T is the torque of the shaft, F is the resultant force, and r is the radius of the blades (hub) see the following equation (3.10).

Results:

The Outlet Velocity C2:

We have the speed of the inlet velocity which will be the speed of the air:

C1 = 100 km/h = 27.78 m/s T02 = T01 = 293 K “Adiabatic process”

T01 = 20 0C = 293 K A2 = 0.026 m2

A1 = 0.062 m2 C2 =? (the outlet velocity)

P01 = 101320 Pa (1.0132 bar)

Step (1): Using equation 3.3 to find T1 (Cp = 1005 J/kg.K):

T1 = 292.616 K

Step (2): Now, we use equation 3.4 to find Mach number at the inlet:

M1 = 0.081

Step (3): Using equation 3.6 to find the Mach number at the outlet:

M2 = 0.197

Step (4): Using equation 3.5 to find the static temperature at the outlet

T2 = 290.74 0K

Step (5): Use equation 3.4 to find the outlet velocity of the nozzle:

C2= 67.33 m/s

Step (6): Find the static inlet pressure by using equation 3.8:

P1 = 100856.597 Pa

Step (7): Find the density at the inlet by using equation 3.7:

kg/m3

Step (8): finally, find the outlet density from the continuity equation (equation 3.9)

kg/m3

The Wind Power Pv :

1.182 kg/m3 the pressure at the outlet nozzle

Av= 0.026 m2 “the outlet area which is directed to the fan”

u = 67.33 m/s “the outlet velocity of the nozzle when the air speed is 27.78 m/s = 100 km/hr”

Pv = 4690.15 Watt
