The well-known Boussinesq (also known as Oberbeck—Boussinesq) approximation is still
the most common approach for the numerical simulation of natural convection problems …

In the present paper, a numerical simulation of natural convection flow in annulus space with
a partially heated inner cylinder is proposed. The numerical investigation is based on lattice …

The electro-thermo-convection of a perfectly insulating liquid lying between a square
enclosure and a heated inner circular cylinder is numerically investigated using a unified …

An investigation is presented of free convection in horizontal concentric annuli of varying
with inner shape where the inner and outer surfaces are kept at a constant temperature. The …

In order to reveal the oscillatory characteristics of the natural convection of nanofluid, this
paper presents a comprehensive numerical work on the oscillatory natural convection of …

Instabilities in the flow of natural convection in a horizontal annulus of radius ratio 2 filled
with fluid of Prandtl number 0.1 are investigated numerically. The investigation largely …

In this paper, we perform a two-dimensional numerical investigation into the electro–
thermoconvection with a melting boundary in horizontal concentric annuli filled with a …

The natural convection heat transfer in a highly insulating liquid contained between two
horizontal concentric cylinders is shown by two-dimensional numerical simulations to be …

This paper presents a series of numerical simulations on natural convection of a water-
based nanofluid near its density maximum in an annulus. The volume fraction of the …

The dynamical and chaotic behaviors of natural convection flow in the semi-annular and full-
annular cylindrical domains are studied using the method of isolation by spectral expansion …
