The propagation of temperature and concentration fields around a deformed gas bubble rising in a quiescent hot or bi‐solution liquid
W.Z. Li, Y.Y. Yan, J.B. HullThis paper is concerned with a numerical study on evolution of a deformed bubble and propagation of the fields around the bubble. The model uses a numerical procedure with the…
Mixing in a tundish and a choice of turbulence model for its prediction
Pradeep K. Jha, Rajeev Ranjan, Swasti S. Mondal, Sukanta K. DashThe Navier‐Stokes equation and the species continuity equation have been solved numerically in a boundary fitted coordinate system comprising the geometry of a single strand bare…
Reactive‐diffusive phenomena in two‐dimensional, anisotropic media
J.I. RamosNon‐linear reaction‐diffusion processes with cross‐diffusion in two‐dimensional, anisotropic media are analyzed by means of an implicit, iterative, time‐linearized approximate…
Numerical simulation of unsteady flow in natural and thermosolutal convection using boundary‐fitted coordinate system
J.M. Zhan, Y.S. LiA numerical scheme is proposed to solve double‐diffusive problems using a boundary‐fitted coordinate system to introduce finer grids in the boundary layer regions and an accurate…
Benchmark solutions for the natural convective heat transfer problem in a square cavity with large horizontal temperature differences
Jan Vierendeels, Bart Merci, Erik DickIn this study, Benchmark solutions are derived for the problem of two‐dimensional laminar flow of air in a square cavity which is heated on the left, cooled on the right and…
Natural convection in enclosures with variable fluid properties
Marcos de Souza, Ricardo Fortes de Miranda, Humberto Araujo MachadoThe generalized integral transform technique (GITT) is an hybrid numerical‐analytical method that has been successfully applied in convection‐diffusion problems, where the…
Effect of surface waviness and aspect ratio on heat transfer inside a wavy enclosure
Prodip Kumar Das, Shohel Mahmud, Syeda Humaira Tasnim, A.K.M. Sadrul IslamA numerical simulation has been carried out to investigate the buoyancy induced flow and heat transfer characteristics inside a wavy walled enclosure. The enclosure consists of…
