Design studies and aerodynamic performance analysis of small scale horizontal axis wind turbine blade for nano-grid applications

Abstract EN

Wind energy, being easily accessible, environmentally friendly, and being cost effectively, has become the world's one o f populargrowing renewable energy sources o f electricity génération.

Among a llo fth e wind turbines, HorizontalAxis Wind Turbine (HA WT) is consideredas leading technology due to its high efficiency.

However, to spread this technology to mankind it is needed to develop turbine in this way that people can use it individually and comfortably.

This kind o f thinkingacceleratesthe advancement ofintegration o fw in d turbine with Nano grid concept Although great progress has been achieved in the wind technology, there is still scopeto reduce the cost and improve the performance ofsmall-scale wind turbines.

Moreover,low wind velocityshouldalso need to be utilizedproperly to achievesaturated energy production.So, concentration is going to small scale wind.

Small scale horizontal axis wind turbines (SSHA WT) provide a clean, prospective and viable option fo r energy supply.

Moreover, SSHA WT can also be acted as one o fth e reliable pow er sources o f Nano grid.To design efficient wind turbine it is required a smooth and continuous development process.

The current study focused on aerodynamic design and performance analysis o f small-scale horizontal axis wind turbine blade using the blade element momentum (BEM)method with most updated and corrected model.

The effects ofthe design parameters o fa small wind turbine such as the blade chord and twist angle distributions on pow er performance were also investigated.

In this study, the pitch is fix ed and speed is variable.

Results show thatthe maximum coefficient ofperformance is .508g at the Tip speed ratio 6.5 which is veryindication in preliminarystage pow er prediction.
