Vertical Cavity With Sidewall Heating
Figure 4-49: Schematic representation of geometry and parameters for the equivalent thermal conductivity correlation applied to a vertical cavity with sidewall heating.
The following correlations correspond to equations 9.50, 9.51, and 9.52 in Ref. 21:
•
If 1 ≤ H ⁄L ≤ 2, 10−3 ≤ Pr ≤ 105, and :

•
If 2 ≤ H ⁄L ≤ 10, Pr ≤ 105, and 103 ≤ RaL ≤ 1010:

•
If 10 ≤ H ⁄L ≤ 40, 1 ≤ Pr ≤ 2 ⋅ 104, and 104 ≤ RaL ≤ 107:

where H is the height of the cavity, L is the distance between the side plates, RaL is computed from L and the temperatures T1 and T2 of the side walls, and Pr = μCp ⁄k. The material data are evaluated at (T1 + T2) ⁄2.
