The efficiency of an electric motor for an unmanned aerial vehicle can reduce when its
temperature exceeds the working temperature. In this paper, air-and water-cooling methods …

In the present study, protrusions in the leading edge of the NACA 4415 airfoil were
incorporated as a passive flow control measure on the wind turbine blades. Three airfoil …

The clustering distribution of vertical axis wind turbines in limited sea areas is a hot direction
in offshore wind power. This study attempts to use biomimetic protuberances to improve the …

The blade profile of the Savonius hydrokinetic turbine has a significant effect on the
performance of the rotor. Many previous numerical and experimental research suggested …

The operating conditions of wind turbines are changeable, and the flow separation limits the
power generation capacity. In order to improve the output power of wind turbines, based on …

Cavitation is an unsteady complex turbulent flow phenomenon that increases the resistance
of propellers and hydrofoils, reduces hydrodynamic efficiency, and erodes surfaces …

A series of wind tunnel tests were carried out to determine the effect of shark scale-based
vortex generators (SSVG) on a NACA 0015 symmetrical airfoil's aerodynamic …

A turbulence model study was performed to analyze the flow around the Tubercle Leading
Edge (TLE) wing. Five turbulence models were selected to evaluate aerodynamic force …

Stall is a complex phenomenon in aircraft that must be suppressed during flight. As a novel
passive control method, bionic leading-edge protuberances (LEPs) have attracted …

This study investigates the influence of leading-edge protuberances (LEP) on the stall
process of airfoils to identify the decisive factor in the effectiveness of LEPs. Owing to its …
