Aerodynamic and mechanical system modeling of a vertical axis wind turbine (VAWT)
2011 International Conference on Electrical and Control Engineering, 2011The Savonious rotor is a slow running vertical axis wind turbine (VAWT) which gets stabilized after a certain period of functioning. This work aims to assess the results of an aerodynamic study concerning a Savonious rotor. The computational fluid dynamics (CFD) is a technique used to solve the airflow around the wind turbine rotor.

The Techniques Used for Performance Prediction of Vertical-Axis Wind Turbines (VAWTs)
2018The theoretical models that have been developed to predict forces acting on lift-type vertical wind turbine blades have been reviewed. These models were categorized into two groups: conservation of momentum-based group and vortex-based group. The comparisons of calculation with experiment between these groups which based on results extracted from ...

A novel magnetic levitated bearing system for Vertical Axis Wind Turbines (VAWT)
Applied Energy, 2012Abstract In this report, a novel magnetic levitated bearing suitable for Vertical Axis Wind Turbines (VAWT) is introduced, fabricated and tested. The bearing system generates a magnetic force, which can support the weight of the wind turbine rotor. A Finite Element Method (FEM) simulation shows how low the torque of this bearing is.

A micro vertical axis wind turbine (vawt) tested in the Jules Verne wind tunnel
2012This paper presents a model reduction approach for constructing lumped RC thermal networks of IGBT-modules of inverters for which heat and subsequent temperature increases vary with time on different scales ranging from nanosecond to second. It was observed that the time-dependent heat and temperature profiles of transistors and diodes of IGBT-modules ...
