Assessment of stress-blended eddy simulation model for accurate prediction of three-straight-bladed vertical axis wind turbine performance (2019)
Presentation / Conference
Syawitri, T. P., Yao, Y., Yao, J., & Chandra, B. (2019, March). Assessment of stress-blended eddy simulation model for accurate prediction of three-straight-bladed vertical axis wind turbine performance. Paper presented at 54th 3AF International Conference on Applied Aerodynamics, Paris, France

The performance of a three-straight-bladed vertical axis wind turbine at low tip speed ratio has been evaluated by detached eddy simulation (DES) with stress-blended eddy simulation (SBES) turbulence model. Two grid topologies around the blades, i.e....

A review of current technical development in vertical axis wind turbine technologies and their braking system for low speed, urban and offshore areas application (2018)
Presentation / Conference
Syawitri, T., Yao, Y., & Chandra, B. (2018, October). A review of current technical development in vertical axis wind turbine technologies and their braking system for low speed, urban and offshore areas application. Paper presented at International Conference of Global Warming and Climate Change 2018, Bangkok, Thailand

Recently, there are growing interests of using Vertical Axis Wind Turbine (VAWT) to harvest wind energy from low wind speed in urban areas to relatively high wind speed in offshore wind farms. Horizontal Axis Wind Turbine (HAWT) has been known to hav...
