Thermal explosions are often influenced by the complex interaction between transport and reaction phenomena. In particular, reactant consumption can promote safer, non-explosive operation conditions of combustion systems. However, in liquids or gases, the presence of forced convection can affect the behaviour of a system, instigating oscillations in the temperature, reactant concentration and v...

For thermal mixed-convection flows, the Nusselt number is a function of Reynolds number, Grashof number and the angle between the forcedand natural-convection directions. We consider flow over a heated cylinder for which there is no universal correlation that accurately predicts Nusselt number as a function of these parameters, especially in opposing-convection flows, where the natural convecti...

Abstract This paper presents a systematic study of flow and heat transfer mechanisms in compressor disk cavity with an axial throughflow under centrifugal buoyancy-driven convection, comparing previously published experimental data. Wall-modeled large-eddy simulations (WMLES) are conducted for six operating conditions, covering range rotational Reynolds number (3.2×105−2.2×106), buoyancy parame...

The paper is devoted to the study of formation stratification in an incompressible fluid due convective laminar flows horizontal layers heated from side. Medium and intensive modes stationary thermal, concentrational thermo-concentrational (in particular thermohaline) convection are considered, which nonlinear flow features manifested, can radically change structure characteristics heat mass tr...
