Abstract

Wind energy is a renewable energy source used to convert wind power to other useful forms of energy like mechanical and electrical energy. This study aimed to design a small scale multi-bladed HAWT for different agricultural applications. A set of wind speed range was used for the design of a small scale multi-bladed horizontal wind turbine. G.I. sheet material and HDPE plastic material were both used for the design. Three levels of independent variables namely: chord length, angle of attack and wind speed setting for both material were considered in the design. All combinations of independent variables were tested in the laboratory. The dependent variables: shaft rotational speed and torque were computed. Using a trial version of a software for statistical analysis, the optimal design for the G.I. was at wind speed 7 m/s, chord length of 10.5 cm and the angle of attack 20°. For the HDPE material, the optimal design was at 7 m/s wind speed, chord length of 9.5 cm and angle of attack 20°. The optimal designs yielded a maximum torque of 0.6 and 0.46 Nm for G.I. and HDPE blade material, respectively. The relationship of torque and power to shaft rotational speed were analyzed. The results generated a Cp of 0.08 for G.I. sheet and 0.09 for HDPE plastic material. It was concluded that the G.I. sheet design was more suitable for different agricultural applications.
