Three-dimensional laminar convection in a parallelepiped with heating of two side walls

Influence of the Geometric Parameter on the Regimes of Natural Convection and Thermal Surface Radiation in a Closed Parallelepiped

“…The solution method used was tested on the problem of spatial thermogravitational convection in a cube [12,[19][20][21]. Table 1 shows that there is a fairly good agreement between the values of the mean Nusselt number on a hot wall at various values of the Rayleigh number and the data of other authors.…”

“…In the central part of the parallelepiped, the temperature and velocity distributions can be fully described with the use of the two-dimensional approximation. Receding from this zone leads to an increase in the infl uence of the boundary layers formed near the vertical walls Y = 0 and Y = 1, which undoubtedly affects the temperature and velocity isolines [12]. In the case of a cubic cavity (A = 1.0), small deviations of all analyzed components, mainly near the surfaces of the lower and upper walls, are observed.…”

“…It should be noted that in [12] the infl uence of the third coordinate on the regimes of natural convection at ε = 0 in a closed parallelepiped was described in detail. In this work, it was established that to describe the integral heat exchange in cubic or more extended interlayers (A ≥ 0), the results of two-dimensional calculations can be used.…”

Laminar natural convection heat transfer and air flow in three-dimensional cubic enclosures with a partially heated wall

“…The pin diameters and the lengths were varied, and the average Nusselt numbers over the cold surface were computed. Terekhov and Ekaid [17] studied three-dimensional laminar free convection in a parallelepiped with heating of two side walls and variation of the height-to-width aspect ratio. The influence of the volume geometry on the three-dimensional flow structure and heat transfer was presented.…”

The approximate analytical solution of the internal problem of conductive and laminar free convection

“…В работе [2] модификацией метода конечных разностей решается краевая сопряженная задача нестационарного конвективного теплопереноса в замкнутой квадратной полости. Ламинарная свободная конвекция внутри параллелепипеда с нагревом боковых стенок численно исследо-вана в работе [3]. Изучению свободной конвек-ции в квадратной области с внутренней перего-родкой методом конечного объема посвящена работа [4].…”
