Effects of thermal boundary conditions on natural convection flows within a square cavity
TL;DR: In this paper, a numerical study to investigate the steady laminar natural convection flow in a square cavity with uniformly and non-uniformly heated bottom wall, and adiabatic top wall maintaining constant temperature of cold vertical walls has been performed.

Natural convection in a square cavity filled with a porous medium: Effects of various thermal boundary conditions
TL;DR: In this paper, the Darcy-Forchheimer model is used to simulate the momentum transfer in the porous medium and numerical results are presented in terms of stream functions, temperature profiles and Nusselt numbers.

Heat flow analysis for natural convection within trapezoidal enclosures based on heatline concept
Tanmay Basak,S. Roy,Ioan Pop +2 more
TL;DR: In this article, heat flow patterns in the presence of natural convection within trapezoidal enclosures have been analyzed with heatlines concept, and the unique solution of heatfunctions for situations in differential heating is a strong function of Dirichlet boundary condition which has been obtained from average Nusselt numbers for hot or cold regimes.
