Passive wake flow control of vertical axis wind turbines in array configurations
Engineering Applications of Computational Fluid MechanicsThis study introduces a passive wake control strategy for vertical axis wind turbine (VAWT) arrays using arc-shaped deflectors. Unlike prior works focusing solely on layout or blade optimization, this research systematically explores the effects of ...

Vectoring Control of Bilateral Parallel Offset Jet: Flow Characteristics and Control Mechanism
AerospaceWe proposed a bilateral parallel offset jet model that enables jet vectoring control without the need for an active high-pressure secondary flow. Flow characteristics, including deflection force, wall pressure distribution, and flow structures, were ...

Passive Control of Viscous Flow via Elastic Snap-Through [PDF]
, 2017 We demonstrate the passive control of viscous flow in a channel by using an elastic arch embedded in the flow. Depending on the fluid flux, the arch may ‘snap’ between two states — constricting and unconstricting — that differ in hydraulic conductivity ...

Morphology, Transport, and Dynamics of Protein Adsorption in Open‐Cell Metal Foam
Advanced Engineering Materials, EarlyView.Stainless steel (SS) open‐cell foams are shown to adsorb more protein per unit area than previously reported 316L SS and chromium oxide surfaces under static and flow conditions. An integrated approach combining 3D pore imaging, flow simulation, and protein adsorption experiments characterizes the foam’s performance.

Advanced Engineering Materials, EarlyView.This perspective reframes additive manufacturing for electrical machines as a qualification‐limited materials and architecture design problem. It links process–structure–property–performance relationships to magnetic, conducting, dielectric, and thermal property windows, highlighting where AM can enable segmented magnetic circuits, permanent magnet ...
