Penetrative Convection in Partly Stratified Rapidly Rotating Spherical Shells [PDF]

open access: yesFront. Earth Sci. 6:189 (2018), 2018
Celestial objects host interfaces between convective and stable stratified interior regions. The interaction between both, e.g., the transfer of heat, mass, or angular momentum depends on whether and how flows penetrate into the stable layer. Powered from the unstable, convective regions, radial flows can pierce into the stable region depending on ...

Numerical investigation of two-component single-phase natural convection and thermal stratification phenomena in a rod bundle with axial heat flux profile

open access: yesNuclear Engineering and Technology, 2022
The most numerical investigations of the thermal-hydraulic phenomena following the loss of the residual heat removal capability during the mid-loop operation of the pressurized water reactor were performed according to simplifications and are not ...

Enhanced visualisation of complex thermofluid data: Vertical and horizontal combined convection and microscale heat transfer cases [PDF]

open access: yes, 2000
Copyright @ 2000 UITIn general, convective heat transfer is an 'n-dimensional' problem where n is well in excess of 3 for steady flows. Traditionally, the method of dimensional analysis results in a small number of dimensionless groups.

Processing of Plastic Film from Potato Starch: Effect of Drying Methods [PDF]

open access: yes, 2022
Starch-based plastics are biodegradable, compostable compounds made of starch and plasticizers from natural sources. Their fabrication involves the starch-plasticizer reaction at 70–100°C followed by cooling and drying.

Instability and Convection in Rotating Porous Media: A Review

open access: yesFluids, 2019
A review on instability and consequent natural convection in rotating porous media is presented. Taylor-Proudman columns and geostrophic flows exist in rotating porous media just the same as in pure fluids.

Convection in Rotating Spherical Fluid Shells [PDF]

open access: yesin "Mathematical Aspects of Natural Dynamos", E. Dormy, A.M. Soward (eds.), Grenoble Sciences and CRC Press, Boca Raton, pp. 119-198, ISBN-13:978-1-58488-954-0, 2007, 2009
The chapter begins with a description of the annulus model of rotationg convection. The basic equations for the spherical problem are then introduced and the onset of columnar convection in spherical shells is discussed. The onset of inertial mode convection is described which prevails at very low Prandtl numbers.

A lattice Boltzmann model for natural convection in cavities [PDF]

open access: yes, 2013
We study a multiple relaxation time lattice Boltzmann model for natural convection with moment–based boundary conditions. The unknown primary variables of the algorithm at a boundary are found by imposing conditions directly upon hydrodynamic moments ...

Scaling relations in large-Prandtl-number natural thermal convection [PDF]

open access: yes, 2017
In this study we follow Grossmann and Lohse, Phys. Rev. Lett. 86 (2001), who derived various scalings regimes for the dependence of the Nusselt number $Nu$ and the Reynolds number $Re$ on the Rayleigh number $Ra$ and the Prandtl number $Pr$.
