This article proposes a Blade Element Momentum (BEM) theory based model applied to
dual rotors wind turbines. Dual rotor wind turbines studied consist of two rotors mounted …

In this article, the design and characteristic research of the coaxial magnetic gear for the
contra-rotating propeller in the premium yacht are presented. The scale-down model of 1/25 …

The innovative dual-rotor counter-rotating wind turbine (CRWT) shows great importance in
the development of offshore wind farms. In this paper, the performance and wake …

A downstream installed contrarotating rotor can efficiently extract the residual kinetic energy
of a wind turbine wake, thus increasing the overall power coefficient. A significant interaction …

Wind energy is anticipated to play a vital role to fulfill the worldwide energy requirements,
whereas existing bare wind turbines can convert only a fraction of flow energy into electricity …

The paper presents a comparative analysis on the steady-state behavior of two counter-
rotating wind turbines with same components, where the generator can operate as a counter …

A small Counter-Rotating Wind Turbine (CRWT) has been proposed and its performance
has been investigated numerically. Results of a parametric study have been presented in …

Wind energy conversion systems play a major role in the transition to carbon-neutral power
systems, and obviously, a special attention is paid in identifying the most effective solutions …

The object of research is a wind generator with counter-rotating blades. A special feature of
this design is the presence of two wind wheels that rotate in opposite directions. Wind …

Ahead of the elaborate rotor optimisation modelling that would support detailed design, it is
shown that significant insight and new design directions can be indicated with simple, high …
