| Summary: | Nowadays, renewable energies are highly demanded as they are sustainable
and environmentally friendly. One of the renewable energy is wind, and it can be
harvested by using a wind turbine. However the power generated in any system
by natural phenomenon has lots of limitations because of the inconsistency in
the supply of the energy by the source. Wind energy from nature environment
has limitation and inconsistency. Sometimes there are wind energy and
sometimes no wind energy. It is mandatory to design a system which produces
continuous and repeated power for the effective use. Also, in some parts of the
country the weather is unpredictable to apply wind turbine system because of
the environment. Hence, the research aimed to design and develop axial fan with
contraction nozzle for Perpetual Motion Energy Harvesting System. The study
focused on the design of a new concept to improve the energy harvested of wind
turbines to be appropriate for the unpredictable wind energy condition in
Malaysia. The concept involves the implementation of axial turbine fan and
concentrator nozzle for Perpetual Motion Energy Harvesting System, to increase
the electricity generated. Although the system used electricity to start, the
implementation of the fan and nozzle should contribute to improve the electricity
harvested by wind turbine system so that the harvested electricity can cover the
used electricity in the system. Before the configuration of fan and nozzle were
fabricated, the concept of axial fan was studied to get the best performance and
then the nozzle was simulated with the use of a program to obtain the high wind
speed in the system. Next the axial fan and contraction nozzle were fabricated
and tested. Results showed that axial fan can produced wind energy with
average speed of 3.6 m/s while the contraction nozzle improved the wind speed
at outlet which average is 4.7 m/s. Then the integrated axial fan and contraction
nozzle were verified for perpetual motion energy harvesting system by analysed
the rotation speed of wind turbine and the output voltage of the turbine generator.
The maximum output voltage that can be generated by perpetual motion energy
harvesting system was 3.7 V using integrated axial fan and contraction nozzle.
The voltage was measured using digital multimeter |
