Abstract

The present work compares 2D and 3D CFD modeling of wind turbine blades to define reduced-order models eroded leading edge arrangements. In particular, following an extensive validation campaign the adopted numerical models, initially qualitative comparison is carried out on flow fields by looking at turbulent kinetic energy color maps. Promising similarities push analysis consequent quantitati...

Flapping wing dynamics are of great interest in many research areas, such as bioinspired systems and aircraft aeroelasticity. The findings the present study provide significant insight into importance leading-edge dynamic incidence on propulsive performance flapping airfoils. main objective is to improve characteristics by adding a pitching conventional NACA0012 airfoil at lower spectrum Reynol...

In order to solve the underwater noise pollution and improve acoustic stealth performance of vehicles, NACA0020 was bionically modified according structure leading edge tubercles humpback fin. The flow field characteristics hydrofoil-turbulent interaction model before after modification were studied by using large eddy simulation FW-H equation. results show that wavy can effectively reduce turb...

as one of the potential ict application areas within organizations, e-learning has come within the sights of organizations for its plethora of possibilities. the most significant feature is that by using leading edge ict, e-learning helps organizations to chart the changes and create a kind of continued educatin within the corporate environment. the present study studies the challanges facing o...
