▪ Abstract Turbulent flows driven by thermal buoyancy are featured by phenomena that pose
a special challenge to conventional one-point closure models. Inherent unsteadiness …

In this paper a review of recent developments of turbulence models for natural convection in
enclosures is presented. The emphasis is placed on the effect of the treatments of Reynolds …

The laminar and turbulent natural-convection flow in a two-dimensional square cavity
heated from the vertical side is numerically calculated up to a Rayleigh number of 10 14 for …

The test results are presented from three Reynolds-stress models (two isotropization of
production models and a quasi-isotropic model) and the standard k—ϵ model for predicting …

The paper reports on recent developments in modelling and numerical computations of
natural and mixed convection based on newly developed quasi-linear algebraic heat flux …

The use of renewable energy sources to improve the thermal conditions of built
environments and hence decreasing the consumption of conventional energy is an …

This title provides the fundamental bases for developing turbulence models on rational
grounds. The main different methods of approach are considered, ranging from statistical …

A computational study of turbulent natural convection in a side-heated near-cubic enclosure
at a high Rayleigh number (Ra= 4.9× 1010) is performed, aimed at gaining a better insight …

In this paper, the natural convection heat transfer in a volumetrically heated liquid pool
under high Rayleigh number (up to 1015) conditions is investigated. The available …

Results of direct numerical simulation (DNS) of turbulent natural convection between two
differentially heated infinite vertical plates for Ra= 5.4× 105 (Versteegh and Nieuwstadt …
