Wind tunnel test results of a new leading edge flap design for highly swept wings, a vortex flap [PDF]

, 1980
A leading edge flap design for highly swept wings, called a vortex flap, was tested on an arrow wing model in a low speed wind tunnel. A vortex flap differs from a conventional plain flap in that it has a leading edge tab which is counterdeflected from ...

Light‐Programmed Localized Supersaturation Enables Ambient Aqueous Synthesis of Highly Crystalline Metal–Organic Frameworks

Advanced Materials, EarlyView.
In the proposed model, a photoinduced nanoreactor uses Cu2O self‐photooxidation to generate localized supersaturation. A metastable supersaturation state first forms a shell, creating a spatially confined environment that restricts reactant exchange; continued Cu release then drives the local environment toward a labile regime that favors predominantly

Numerical Analysis and Experimental Research of Multi-blade Centrifugal Fan based on Leading-edge Serrated Blade

Zhileng xuebao, 2019
A serrated leading-edge blade for a multi-blade fan of an air conditioner is designed. The main objective is to reduce the vortex near the blade, thus reducing the flow loss and aerodynamic noise of the flow field of the multi-blade fan.

Giant Nonequilibrium Valley Control via Spin‐Selective Hot‐Carrier Transfer in an Antiferromagnetic van der Waals Stack

Advanced Materials, EarlyView.
Spin‐selective hot‐carrier transfer across CrSBr/WSe2/CrSBr interfaces couples the continuously tunable magnetic configuration of antiferromagnetic CrSBr to the valley degrees of freedom of monolayer WSe2, enabling giant nonequilibrium valley control and magnetic‐state‐dependent reversal of circularly polarized emission.

Low speed aerodynamic characteristics of 60 degrees rounded leading-edge delta wing with vortex flaps

, 1996
Low speed wind tunnel studies have been conducted to investigate the effect of vortex flaps with a rounded leading-edge on delta wing performance. Measurements were done using the 60º delta wing at a Reynolds number based on the centre line chord 8x10(5).

Inverse Design of Nanoparticulate Materials

Advanced Materials, EarlyView.
Inverse design shifts nanomaterial development from empirical trial‐and‐error to predictive model‐driven strategies. It can rely on knowledge‐based, data‐based, or hybrid process and property functions. This perspective article provides a practical framework for applying inverse design based on instructive examples. It discusses which modeling approach

Tip leakage vortex characteristics and phase distribution in a helico-axial multiphase pump at different flow rates

Engineering Applications of Computational Fluid Mechanics
This study investigates tip leakage vortex (TLV) characteristics in helico-axial multiphase pumps at 20% inlet gas void fraction across three flow rates (Q/Qdes = 0.9, 1.0, 1.1).
