Turbulent Rayleigh–Bénard convection of water in cubical cavities: A numerical and experimental study

High Rayleigh number convection in a cubic cell with adiabatic sidewalls

“…Convection in a cubic cavity with vertical temperature difference is characterized by number of regimes and was studied extensively for moderate values of Rayleigh number Ra < 10 8 [14][15][16][17][18]. The specific feature of convective flows under vertical temperature difference is their three-dimensional structure even at small supercriticalities.…”

Numerical simulation and comparison with experiment of natural convection between two floors of a building model via a stairwell

“…Ideally, it is desirable to obtain the wall temperatures or heat fluxes as part of the solution. Depending on the problem, it may be possible to set the boundary conditions on the external walls [17,18]. The resulting conjugate heat transfer problem would provide the internal wall temperatures.…”

Numerical Study of Natural Convection in Enclosed Volume

“…Естественная конвекция при незначительных перепадах температур успешно описывается в приближении Буссинеска [5][6][7][8][9]. Данный метод подразумевает линейную зависимость плотности от температуры в условиях несжимаемой среды, что существенно упрощает решение [10,11] Цель проведенного исследования -определение оптимальных граничных условий для моделирования естественной конвекции воздуха в помещении.…”
