Investigating the cooling of solar photovoltaic modules under the conditions of Riyadh
Journal of King Saud University: Engineering Sciences, 2023 Cooling enhances the energy conversion efficiency and output of photovoltaic (PV) panels. In this work, the effects of natural convection, forced convection, and evaporative cooling on the performance of polycrystalline PV panels were investigated.

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 ...

Double MRT Thermal Lattice Boltzmann Method for Simulating Natural Convection of Low Prandtl Number Fluids [PDF]
Int. J. Numer. Methods Heat Fluid Flow, 26(6), pp. 1809-1909, 2016, 2016 The purposes of this paper are testing an efficiency algorithm based on LBM and using it to analyze two-dimensional natural convection with low Prandtl number. Steady state or oscillatory results are obtained using double multiple-relaxation-time thermal lattice Boltzmann method. The velocity and temperature fields are solved using D2Q9 and D2Q5 models,

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).

A “poor man’s” approach to topology optimization of natural convection problems [PDF]
Structural And Multidisciplinary Optimization, 2018 Topology optimization of natural convection problems is computationally expensive, due to the large number of degrees of freedom (DOFs) in the model and its two-way coupled nature.

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.

Effect of heated wall inclination on natural convection heat transfer in water with near-wall injection of millimeter-sized bubbles [PDF]
, 2017 Natural convection heat transfer from a heated wall in water with near-wall injection of millimeter-sized bubbles is studied experimentally. Velocity and temperature measurements are conducted in the nearwall region.

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 ...
