Experimental effects of wing location on wing-body pressures at supersonic speeds [PDF]
An experimental study was performed at supersonic speeds to measure wing and body spanwise pressure distributions on an axisymmetric-body delta wing model on which the wing vertical location on the body was systematically varied from low- to high-mounted

Early evolutionary history of the seed
Biological Reviews, EarlyView.ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Numerical and Experimental Study on Heat Transfer Enhancement by Vortex Generation
Journal of Engineering and Sustainable Development, 2006 Numerical and experimental study was carried out on heat transfer enhancement using a slender delta wing vortex generator to generate longitudinal vortices in a rectangular duct. Numerically, laminar with constant wall temperature was considered. Effect

Synthetic Wind Estimation for Small Fixed-Wing Drones
AtmosphereWind estimation is crucial for studying the atmospheric boundary layer. Traditional methods such as weather balloons offer limited in situ capabilities; besides an Air Data System (ADS) combined with inertial measurements and satellite positioning is ...

Business Strategy and the Environment, EarlyView.ABSTRACT Ensuring the resilience of industrial symbiosis networks (ISNs) has emerged as a key concern in the literature. However, existing studies focus on network‐level strategies, neglecting the potential benefits derived from strengthening the links between symbiotic partners.

Unsteady CFD Analysis of a Delta Wing Fighter Configuration by Delayed Detached Eddy Simulation [PDF]
, 2008 While the flow physics of generic delta wings with sharp leading edges are largely understood, realistic configurations with rounded leading edges and canards are still of scientific and industrial interest.

Energy Landscapes in Chemical Reactions and Transport
ChemPhysChem, Volume 26, Issue 6, March 15, 2025.Kinetics/dynamics of chemical reactivity and transport of chemical species in a solid are both determined by the energy landscape in which they take place. Discussing common grounds but also distinct differences may help in advancing the understanding in both fields.
