Diffusion-free Dynamics in Rotating Spherical Shell Convection Driven by Internal Heating and Cooling

The Astrophysical Journal
The bulk properties of convection in stellar and giant planet interiors are often assumed to be independent of the molecular diffusivities, which are very small.

Investigating the effects of employing a cooling radiator on MHD natural convection by injecting MWCNTs into water

Ain Shams Engineering Journal, 2023
One of the best methods in thermal engineering for cooling a liquid is to use a radiator. Using the radiator mechanism in free convection systems is a successful and first idea to improve performance of natural convection systems, which have various ...

Cooling photovoltaic panels with air convection – Parametric environmental and economic analysis with case studies

e-Prime: Advances in Electrical Engineering, Electronics and Energy
Photovoltaic (PV) panels generate electricity due to photoelectric effect, harvesting solar radiation from the sun. However, the hit of photons on the upper surface of the PV panel increases its temperature, and as a result, decreases its efficiency. The

Modelling the effect of free convection on permafrost melting rates in frozen rock clefts [PDF]

The Cryosphere
This research develops a conceptual model of a karst system subject to mountain permafrost. The transient thermal response of a frozen rock cleft after the rise in the atmospheric temperature above the melting temperature of water is investigated using ...

USING MODES OF FREE OSCILLATION OF A ROTATING VISCOUS FLUID IN THE LARGE-SCALE DINAMO [PDF]

Vestnik KRAUNC: Fiziko-Matematičeskie Nauki, 2013
Considered a model of large-scale magneto-convection in a roteting spherical shell. Velocity expressed of the one of the modes of free oscillation of a viscous conduction fluid in the shell. The stationary modes of convection were found.

When, Where and to What Extent Do Temperature Perturbations Near Tropical Deep Convection Follow Convective Quasi Equilibrium?

Geophysical Research Letters
Convective Quasi‐Equilibrium (CQE) is often adopted as a useful closure assumption to summarize the effects of unresolved convection on large‐scale thermodynamics, while existing efforts to observationally validate CQE largely rely on specific spatial ...

Transition of thermally induced flow in a square cavity using Spectral Method [PDF]

E3S Web of Conferences
This study presents a novel mesh-free method for simulating natural convection in a square cavity filled with Newtonian fluid. The proposed algorithm integrates mesh-free Spectral methods with the Moving Collocation Element (MCOE) technique and employs a

Numerical investigation of the combined effect of forced and free thermal convection in synthetic groundwater basins

Journal of Hydrology, 2019
The theoretical examination of the combined effect of water table configuration and heat transfer is relevant to improve understanding of deep groundwater systems, not only in siliciclastic sedimentary basins, but also in fractured rocks or karstified ...
