Research Abstract

We studied the performance estimation of the straight winged vertical axis wind turbine by means of numerical analysis and a field test. Through the investigation, we could confirm that the SWVAWT can reach the performance, which can be commercially realized. In numerical simulation, we have tested the performance test of the turbulence models as the first step for the flow around a single wing. It was necessary to find an appropriate model with a rather rough meshing, so that rotating wing analysis can be performed. In this study, we found that a DES analysis with Spalart-Allmaras model is the best way of our numerical simulation. We applied this model to the analysis of rotating wind turbine with three NACA0018 wings. By performing unsteady flow analysis, we obtained an optimal design condition of the wind turbine to be with a solidity of 0.079 and the tip speed ratio of 3.75, which gave power coefficient of 0.45. In the field test, we have developed a control system, which enables the operation of constant tip speed ratio, as well as braking system to avoid over-rotation. Through stand-alone operation we could confirm the power coefficient to be close to the on by theory at the tip speed ratio of 3.
