Muhammad Kemal Ganie ABSTRACT

DEVELOPING 3-BLADED HELICAL VERTICAL AXIS WIND TURBINE BLADE FOR LOW SPEED WIND

By

Muhammad Kemal Ganie Dena Hendriana, M.Sc., Ph.D , Advisor

SWISS GERMAN UNIVERISTY

The purpose of this thesis is to perform a research on the design of Helical VAWT (Vertical Axis Wind Turbine). It is known that savonius turbine’s maximum TSR (Tip Speed Ratio) to produce maximum power output can’t exceed 1 because of it’s dependency with drag force caused by the water. The idea is by twisting the blade, we can channel the air flow comes from the top of the blade to the bottom of the blade thus increasing the maximum TSR of the blade. The twisting angle will be determined by the ratio of it’s height and diameter.

CFD (Computational Fluid Dynamic) will be used to simulate the design that is created using SolidWork. This thesis project is focusing on the efficiency of the design created using Solidwork and tested in the simulation program called CFD(Computational Fluid Dynamic) and later will be compared with the real design which will be tested on the rooftop of Swiss German University.

Keywords: Helical VAWT, Vertical Axis Wind Turbine, CFD, Computational Fluid Dynamic, Savonius, Paraview,OpenFOAM, Solidworks.
