Triangular enclosures are typical configurations found in attic spaces of residential as well as industrial pitched-roof buildings. Previous studies on airflow within such spaces have focused on the laminar range. A numerical study has been carried out for time-dependent, two-dimensional low turbulence natural convection of air contained in the attic of a pitched roof of triangular crosssection...

In present study, a 2D rectangular enclosure was considered as latent thermal energy storage (LTES) system. Lauric acid used PCM material. The aim of this study to use fins enhance melting process PCM. Position and shape double were investigating parameters. At first stage three different positions for shape. Results indicated that amongst aforementioned cases, best results achieved when locate...

Thermal and flow fields due to laminar steady natural convection in a triangular enclosure having thick conducting sidewalls have been investigated numerically. Inclined left right side walls are maintained at isothermal cold temperatures while the bottom wall is hot temperature. Problem has analyzed non-dimensional governing equations solved using finite volume approach employing more nodes fl...
