Natural Convection from a Corrugated Heated Surface at the Bottom of Vented Rectangular Enclosure
TL;DR: In this article, the effects of the angle of opening of the corrugated surface, opening ratio, enclosure's tilt angle, and Rayleigh number on the passive cooling of the enclosure were investigated.
Journal ArticleDOI
Statistical analysis of turbulent thermal free convection over a small heat source in a large enclosed cavity
TL;DR: In this paper, the authors investigated the thermal boundary layers and the center and border of the hot plate in an enclosed cavity, and showed that the efficiency of energy transformation from large scales to smaller ones enhances with increased height and reaches an acme at the height of 5-8mm.

An immersed boundary method to conjugate heat transfer problems in complex geometries. Application to an automotive antenna
Federico Favre,Federico Favre,Oscar Antepara,C. Oliet,Oriol Lehmkuhl,Carlos David Pérez-Segarra +5 more
TL;DR: An IBM was extended to simulate problems with conjugate heat transfer boundary conditions taking into account the radiative exchange between surfaces, resulting in a monolithic methodology for the simulation of realistic situations, where all three heat transfer mechanisms can be considered in complex geometries.

Mathematical modelling of conjugate laminar and turbulent heat transfer in a cavity: Effect of a vertical glazed wall
TL;DR: In this article, a numerical analysis of the laminar and turbulent natural convection combined with surface thermal radiation in a square cavity with a glazed wall is presented, where the enclosure is composed of one left vertical isothermal wall, two horizontal adiabatic walls and one right vertical partially semitransparent wall.

A numerical study of three-dimensional natural convection in a differentially heated cubical enclosure
TL;DR: In this article, a high-resolution, finite difference numerical study is reported on three-dimensional steady-state natural convection of air, for the Rayleigh number range 103⩽ Ra ⩽ 106, in a cubical enclosure, which is heated differentially at two vertical side walls.
