Abstract

A conceptual design of wind accelerating device was developed for small VAWT wind turbine with the objective of improving incoming wind speed before reaching and subsequently hitting the turbine blades. Low wind speed particularly in Malaysia need to overcome in order to improve the wind turbine efficiency in harvesting potential wind energy into electricity. In this thesis, the Theory of Inventive Problem Solving (TRIZ) was used in order to produce an idea in generating solutions to the problem. TRIZ contradiction matrix and 40 inventive principle solution tools has been applied in the early stage of solution generation. Based on the general solutions, the most relevant principles with respect to the design intent are selected as a guideline to develop the device. Two different concepts with working condition similar to wind vane are designed using CAD software (CATIA), focussing particularly on the main part namely head of the wind accelerating device. In addition, the device is also designed with the intention of sharing the same pole of the VAWT wind turbine. The performance of the device was further analysed using CFD method (ANSYS) with various wind speed with the aim of increasing incoming wind speed after passing through the wind accelerating device.
