Abstract:

Conjugate heat transfer from a surface-mounted block (31x31x7 mm³) to forced convective air flow (1-7 m/s) in a parallel-plate channel was studied experimentally and analytically. Particular attention was directed to the heat flow from the block to the floor. The concepts of adiabatic wall temperature (T_ad) and adiabatic heat transfer coefficient (h_ad) were employed to account for the effect of thermal wake and shed from the block on the heat transfer from the floor. The experimental data of T_ad and h_ad were used in setting the boundary condition for the numerical analysis of conductances for different heat flow paths was proven experimentally. The heat conduction analysis code was then used to find the heat transfer capability of various block-support/floor combinations.
