ABSTRACT
Design and aerodynamic performance analysis
of 10
KW horizontal axis wind turbine (HAWT) rotor blades are carried out.
The blade
geometry is calculated under consideration that the drag is equal to
zero to
obtain the optimal blade geometry. Drag effect is included in
theoretical
performance calculation. The theoretical performance results showed
that the
maximum power coefficient was 0.46 at tip speed ratio equal to 5.5.
This value
compared well with available research data. The experimental model had
been
built and tested using a low speed open wind tunnel.
The validation of the theoretical results has
been conducted at single low tip speed ratio. The study between
theoretical
result and experimental measured performance in the torque and power
coefficient region for one value of tip speed ratio resulted in good
agreement.
