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 reliability of blades is vital to the system reliability of a hydrokinetic turbine. A time-
dependent reliability analysis methodology is developed for river-based composite …

Marine renewable energy holds strategic potential in Indonesia, not only to meet the target
of renewable energy share in the national energy mix but also to provide equal access to …

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 …

An ocean current power generator is a power plant that uses kinetic energy from ocean
currents to generate electricity. Considering that the blade is the component that receives …

Variable-pitch (VP) technology is an effective approach to upgrade the aerodynamics of the
blade of an H-type vertical-axis wind turbine (VAWT). At present, most of the research efforts …

This study examines an innovative turbine with the addition of the number and arrangement
of straight blade cascaded (SBC). SBC is a combination of passive variable-pitch and fixed …

If the pitching hydrofoil moves following a circular trajectory, the turbine can use multiple
hydrofoils to capture energy from the current, which has the potential to improve efficiency. In …

Wind energy became one of the most significant renewable energy resources in the last
decades. A wind turbine is used to harvest kinetic energy from wind and convert it into …

In previous study (Chen et al., 2018), performances of a fixed pitch and a sinusoidal pitch H-
Darrieus vertical-axis turbine (VAT) are compared by numerical simulations. With an …
