Unlike horizontal axis wind turbines (HAWTs), the Darrieus vertical axis wind turbine (H-type
VAWT) has been the subject of only a few recent studies directed at improving its self …

The Darrieus vertical axis wind turbine (VAWT) has been the subject of a large number of
recent studies to improve self-starting capability and aerodynamic performance. This study …

This study, firstly, provides an up-to-date global review of the potential, technologies,
prototypes, installed capacities, and projects related to ocean renewable energy including …

Power generation utilizing the kinetic energy of river flow, tidal, and ocean currents have
encouraged the use of Darrieus turbines. However, the low power coefficient, poor self …

The present study aims to explain the characteristics of a vertical-axis lift-type hydrokinetic
rotor in its startup stage. The rotor is equipped with three helical blades. The effect of the …

The performance prediction of two counter-rotating vertical axis hydrokinetic turbines is
presented in this paper. The flow field is governed by the 3D time-dependent incompressible …

Qeshm channel between the Persian Gulf and Oman Sea with a maximum tidal current
velocity of about 2 m/s is unsuitable for installing conventional tidal turbines. This study aims …

In this study, the CFD method is carried out in the wake region of an H-type Darrieus
hydrokinetic turbine. The hydrodynamic investigation was examined with symmetric and non …
