Rectangular enclosures inclined

Attention will here be restricted here to flow in a rectangular enclosure as shown in Fig. 8.24. In general, the enclosure is inclined to the vertical as illustrated in Fig. 8.24. For simplicity, in order to illustrate how enclosure flows can be analyzed, it will be assumed that one wall of the enclosure (AB in Fig. 8.24) is at a uniform high temperature, Th, and that the opposite wall (CD in Fig. 8.24) is at a uniform low temperature, Tc Two boundary conditions on temperature are usually considered on the two remaining end walls (BC and DA in Fig. 8.24). If these walls are made from a material that has a low thermal conductivity, it is usual to assume that these walls are adiabatic, i.e., that there is no net heat transfer to or from the wall at any point on the wall. Alternatively, if these walls are made from a material that has a relatively high thermal conductivity, it is usual to assume that these walls are perfectly conducting and that the temperature on these end walls varies linearly with distance from the hot wall from T to Tc-... [Pg.386]

An inclined rectangular enclosure with isothermal surfaces. [Pg.540]

Attention will here be restricted to two-dimensional steady flow in a rectangular porous medium -filled enclosure which is, in general, inclined at an angle to the vertical. One wall of the enclosure is kept at a uniform high temperature and the opposite wall is kept at a uniform low temperature. The o her two walls of the enclosure are assumed to be adiabatic, i.e., it is assumed that no heat is transferred into or out of these walls. The situation is, therefore, as shown in Fig. 10.27. [Pg.532]
