Effect of natural convection on oscillating flow in a pipe with cryogenic temperature difference across the ends [PDF]
, 2012 The effect of natural convection on the oscillatory flow in an open-ended pipe driven by a timewise sinusoidally varying pressure at one end and subjected to an ambient-to-cryogenic temperature difference across the ends, is numerically studied ...

Natural convection reactor [PDF]
, 1956 A previous report described the conceptual design of a plutonium producing reactor that may be characterized as follows: Power output (2000 MW); cooling - (natural convection of light water through the reactor, up through a draft tube to an evaporative cooling pond, then back to the reactor, and fuel (400 to 500 tons of uranium enriched to 1.2% U-235).

Convection Reconciles the Difference in Efficiencies Between Low-Mass and High-Mass Common Envelopes [PDF]
, 2022 The formation pathways for gravitational-wave merger sources are predicted to include common envelope (CE) evolution. Observations of high-mass post-common envelope binaries suggest that energy transfer to the envelope during the CE phase must be highly efficient.

Morphological Attractors in Natural Convective Dissolution [PDF]
Physical Review Letters, 2022 Recent experiments demonstrate how a soluble body placed in a fluid spontaneously forms a dissolution pinnacle -- a slender, upward pointing shape that resembles naturally occurring karst pinnacles found in stone forests. This unique shape results from the interplay between interface motion and the natural convective flows driven by the descent of ...

Viscoelastic Natural Convection [PDF]
, 2012 Heat convection occurs in natural and industrial processes due to the presence of temperature gradients which may appear in any direction with respect to the vertical, which is determined by the direction of gravity. In this case, natural convection is the fluid motion that occurs due to the buoyancy of liquid particles when they have a density ...

On the convective nature of roll waves instability [PDF]
Journal of Applied Mathematics, 2005 A theoretical analysis of the Saint‐Venant one‐dimensional flow model is performed in order to define the nature of its instability. Following the Brigg criterion, the investigation is carried out by examining the branch points singularities of dispersion relation in the complex ω and k planes, where ω and k are the complex pulsation and wave number

Numerical prediction of mixed convection heat transfer in an enclosure [PDF]
, 2012 In this article the transport mechanism of laminar mixed convection in a shear and buoyancy driven cavity flow with locally heated lower wall and moving cooled sidewalls is numerically studied using cubic interpolation profile method.
