Floating vertical-axis wind turbines (VAWTs) display considerable advantages over
horizontal-axis wind turbines (HAWTs) due to their Omni directionality, better structural …

A parametric study of vertical axis turbines of the H-Darrieus type is conducted using state-of-
the-art Computational Fluid Dynamics (CFD) and the k-ω Shear Stress Transport RANS …

Turbulence is one of the main characteristics of urban flows, but its effect on the performance
of small VAWTs (often used in urban wind installations) has not been thoroughly …

Vertical-axis wind turbines do not need to be oriented to the wind direction and offer direct
rotary output to a ground-level load, making them particularly suitable for water pumping …

This paper reviews the initial development of the design and operation of modern vertical
and horizontal axis wind turbines, with the aim of comparing the development of the two …

In this paper, numerical simulations are conducted to compare the performances of a fixed-
blade vertical-axis turbine (VAT), and a variable pitch VAT whose blades are forced to do …

Maintaining high power generation for small lift-driven vertical axis wind turbines in a
changing wind environment has not been well studied yet, due to the challenges inherited …

In this study, a conceptual co-axial contra-rotating vertical axis wind turbine (CR-VAWT) is
conceived by splitting the single conventional vertical axis wind turbine (C-VAWT) blade …

This paper describes the performance of a micro vertical-axis wind turbine with variable-
pitch straight blades. The proposed variable-pitch angle mechanism has an eccentric point …

This paper provides a summary of the work done at DPA on numerical and experimental
investigations of a novel patented vertical axis and variable pitching blades hydro turbine …
