Scaling regimes in spherical shell rotating convection [PDF]
Journal of Fluid Mechanics, 2016 Rayleigh–Bénard convection in rotating spherical shells can be considered as a simplified analogue of many astrophysical and geophysical fluid flows. Here, we use three-dimensional direct numerical simulations to study this physical process. We construct

On the efficiency of a radiant heating regenerative system
Вестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2017 A scheme of a radiant heating regenerative system is developed on the basis of a two-flow heat generator, a system and form of heat-radiating air ducts is proposed.

Nature, 1962 It is natural to inquire whether thermal convection is occurring in the Moon through solid state creep processes. The primary evidence is the departure of the Moon from the figure of hydrostatic equilibrium, but certain difficulties in the thermal history of the Moon are eased by assuming heat transfer by convection. If convection exists in the Moon it

Walailak Journal of Science and Technology, 2014 In this study, we analyze the effects of thermal radiation and chemical reaction on the steady 2 dimensional stagnation point flow of a viscous incompressible electrically conducting fluid over a stretching surface, with suction and heat generation.

Convection and oscillations [PDF]
Astronomische Nachrichten, 2010 AbstractIn this short review on stellar convection dynamics I address the following, currently very topical, issues: (1) the surface effects of the Reynolds stresses and nonadiabaticity on solar‐like pulsation frequencies, and (2) oscillation mode lifetimes of stochastically excited oscillations in red giants computed with different time‐dependent ...

Heat transfer and large scale dynamics in turbulent Rayleigh-Bénard convection [PDF]
, 2008 The progress in our understanding of several aspects of turbulent Rayleigh-Benard convection is reviewed. The focus is on the question of how the Nusselt number and the Reynolds number depend on the Rayleigh number Ra and the Prandtl number Pr, and on ...

Advanced Engineering Materials, EarlyView.This study identifies 12 wt% indium (In) as the optimal composition for Sn0.5Ag0.7Cu5Bi solder joints, achieving 87% ductile fracture and 81% suppression of intermetallic compound (IMC) growth versus 4 wt% In. High‐In alloys (15–17 wt%) show abnormal IMC thickening due to thermal activation.

Advanced Engineering Materials, EarlyView.A simple, cleanroom‐free method produces flexible mini‐coils using automated blade cutting. The process is fast, low‐cost, and supports diverse materials. The coils show strong durability and performance under repeated bending. Demonstrated use in resistor‐inductor filters and magnetic nanoparticle control proves their adaptability.

Mind the Gap - Part 3: Doppler Velocity Measurements From Space
Frontiers in Remote Sensing, 2022 Convective motions and hydrometeor microphysical properties are highly sought-after parameters for evaluating atmospheric numerical models. With most of Earth’s surface covered by water, space-borne Doppler radars are ideal for acquiring such ...
