Computational Optimization of Adaptive Hybrid Darrieus Turbine: Part 1
Fluids, 2019 Darrieus-type Vertical Axis Wind Turbines (VAWT) are promising for small scale decentralized power generation because of their unique advantages such as simple design, insensitive to wind direction, reliability, and ease of maintenance.

Effect of the number of blades and solidity on the performance of a vertical axis wind turbine [PDF]
, 2016 Two, three and four bladed phgr-shape Vertical Axis Wind Turbines are simulated using a free-wake vortex model. Two versions of the three and four bladed turbines are considered, one having the same chord length as the two-bladed turbine and the other ...

A linear systems analysis of the yaw dynamics of a dynamically scaled insect model [PDF]
, 2010 Recent studies suggest that fruit flies use subtle changes to their wing motion to actively generate forces during aerial maneuvers. In addition, it has been estimated that the passive rotational damping caused by the flapping wings of an insect is ...

Effect of Rotational Speed Variation on the Flow Characteristics in the Rotor-Stator System Cavity
Applied Sciences, 2021 In this paper, to study the effect of dynamic and static interference of clearance flow in fluid machinery caused by changes in rotational speed, the model was simplified to a rotor-stator system cavity flow. Investigating the flow characteristics in the

On Hirth Ring Couplings: Design Principles Including the Effect of Friction [PDF]
, 2018 Rings with Hirth couplings are primarily used for the accurate positioning of axial-symmetric components in the machine tool industry and, generally, in mechanical components. It is also possible to use Hirth rings as connection tools.

Three-Bladed Horizontal Axis Water Turbine Simulations with Free Surface Effects
International Journal of Applied Mechanics and Engineering, 2021 The water level above a hydrokinetic turbine is likely to vary throughout the season and even along the day. In this work, the influence of the free surface on the performance of a three bladed horizontal-axis turbine is explored by means of a three ...

Two-scale momentum theory for very large wind farms [PDF]
, 2016 A new theoretical approach is proposed to predict a practical upper limit to the efficiency of a very large wind farm. The new theory suggests that the efficiency of ideal turbines in an ideal very large wind farm depends primarily on a non-dimensional ...
