Project Name : Utilising the concept of steam engines
Theme Name : Transport & Communication
Scientific Principle: Utilising the concept of steam engines.
Method Procedure
This cycle has three major components:
(1) Boiler (in this case the water cylinder).
(2) Turbine to which the piston is connected.
(3) Condenser.
(4) Pump.
When we speed up a car intense heat is produced inside the silencer of the main engine which can easily boil water at 1 atm. We have prepared a model to reduce this wastage of heat.
Mechanism:
(1) The heat from the silencer of the main engine (kept inside the water cylinder of the supporting engine) enters the water cylinder.
(2) The water is heated into steam in the boiler (water cylinder).
(3) The water gets converted into super heated steam, with intense pressure inside it, just like our home pressure cookers.
(4) The enthalpy of the water increases.
(5) The kinetic energy of the steam also increases.
(6) This kinetic energy is utilised to rotate the turbine of the car.
(7) Now, to the turbine the shaft is connected, to which the piston is connected.
(8) To the piston the axle of the wheel is connected.
(9) The steam does some work through the turbine.
(10) So the enthalpy of the steam decreases.
(11) Now this steam is made to pass through a condenser.
(12) Here this steam is converted back to water (liquid).
(13) The enthalpy of the steam decreases as heat is taken out of the steam.
(14) Now this liquid is pumped from a low pressure area to a high pressure area through the pump.
(15) Here a s work is done on the liquid the enthalpy of the liquid increases.
(16) The liquid is made to enter into the boiler (water cylinder), gets heated, the gets converted into steam, and the process continues…
Now as the blades of the turbine rotate so the shaft connected to the turbine rotates, making the piston rotate, making the axle of the wheel to rotate. So the speed of the car increases. The car’s speed gets boosted up ,and as a result the car can travel the same distance in less time thus making the petrol/diesel consumption less. The original concept come from steam engine, the only difference being that here the water is reused unlike in steam engine where the steam gets wasted.
Advantage:-This is a self sufficient and self adjusting technique, as the water gets reused again and again. This process starts automatically when the silencer’s heat gets increased when the speed of the car increases to about 70-80 km/hr. We can also use this system according to our need. The petrol is also conserved in this case. the process is also thermal efficient. Suppose we could travel 30 km in 2 litres of petrol in 2 hours initially. Now buy implementing this system the speed of the cars can be increased. Thus we can now travel 30 km in just (suppose)1 hour and automatically the petrol consumption will reduce, and so will the price get reduced. So this process can prove veryadvantageous for us if we implement this in the cars, for both us and the environment.
Unique Features of the Project:
(1) Heat generated by the system is used.
(2) Reducing petrol usage
(3) Reusing of water.
(4) Self-adjusting system.
Applications in real life: Basically it could be used in vehicles for example in cars, buses. Also it could be used in various machines in factories where heat production is large and the heat is not utilised.
Further scope of the project: With the advent of lighter (alloys) weight vehicles these components of the subsidiary engine could be used out there as due to in vehicles nowadays this system might be heavier. Also it could be used in various machines where heat generated gets wasted..
