Natural convection over vertical and horizontal heated flat surfaces: A review of recent progress focusing on underpinnings and implications for heat transfer and environmental applications

The Physics of Fluids, 2021
Natural convection arising over vertical and horizontal heated flat surfaces is one of the most ubiquitous flows at a range of spatiotemporal scales. Despite significant developments over more than a century contributing to our fundamental understanding ...

External Natural Convection [PDF]

open access: possible, 1992
Numerical calculation from the full differential equations for convection in an unbounded region is expensive, and hence approximate solutions are important. For small values of the Rayleigh number Ra, perturbation methods are appropriate. At large values of Ra thermal boundary layers are formed, and boundary layer theory is the obvious method of ...

Natural convection of a viscoelastic fluid [PDF]

open access: possibleRheologica Acta, 1982
The influence of elasticity and shear thinning viscosity on the temperature distribution and heat transfer in natural thermal convection is discussed. The numerical investigations are based on a four-parameter Oldroyd constitutive equation, which represents the typical fluid response of dilute solutions and melts.

Comparative Heat Transfer Analysis of MoS2/C2H6O2 and SiO2-MoS2/C2H6O2 Nanofluids with Natural Convection and Inclined Magnetic Field

Journal of Nanofluids, 2020
This article explores the comparative analysis of MoS2/C2H6O2 nanofluid and SiO2-MoS2/C2H6O2 hybrid nanofluid natural convective boundary layer flow through a stretching area. Uniform inclined magnetic field is applied together with viscous dissipation.

NATURAL CONVECTION IN A SEMIELLIPTIC CAVITY

Numerical Heat Transfer, 1987
Natural convective steady-state motion inside a bidimensional semielliptic cavity is investigated numerically by means of a finite-element algorithm. The ceiling of the cavity is kept at a known temperature with a sinusoidal spatial distribution and the floor is assumed thermally insulated.
