CONVERGENT WIND MILL WITH VELOCITY AND ACCELERATION CONTROL Albert Francis Aa, Balachandran Ab, Chellakarthikeyan R.Mc UG Students, Department of Mechanical Engineering, K.Ramakrishnan College Of Engineering, Tiruchirappalli,Tamilnadu,India-621112. ---------------------------------------------------------------------***--------------------------------------------------------------------A,b,c
Abstract: This paper is related to effect of blade design and ratio of convergent nozzle’s inlet and outlet.The improvement of angled fan blades rotating radius is to calculate the velocity.The convergent wind mill is to control the velocity of air in various direction by using convergent nozzles in four directions.The outlet area of nozzle is half of the inlet area.The exit area of nozzle is partially closed and it controls the velocity of air.The wind force is effectively passed through horizontal axis vertical blades by using convergent nozzles. Key words Renewable energy,convergent nozzles,blade angle,velocity,power. 1.INTRODUCTION
There are many renewable energy sources around us.We are not utilizing these sources completely.But we are using high power obtained by non renewable energy sources.The finite sources will be extinct in future.So we are planning to utilize the flow of air(wind) to generate power from various places.Because it is the most independent and non polluted renewable energy source in the world.Energy cannot be created but it is converted from one form to another form. Modern devices(such as TV, fan,machines,etc)are running with the help of input energy.The fossil fuels gives high power and high efficiency for a certain period only.But the wind energy is can produce small amount of power forever . 2.SCENARIO Tamilnadu`s power producing capacity by wind is 29% of india`s total power.The report says that the maximum power recruitment in india.

3.OBJECTIVE
To reduce the electricity shortage in rural and urban areas,
To increase the efficiency when compared to existing methods,
To reduce the weight of the apparatus ,initial and maintenance cost,
To reduce the size of the design and to obtain high power,
To create job opportunities in wind power stations and it will reduce the unemployment problems.
