Abstract

It is a common phenomenon that
the devices that are exposed to constant heat fluxes are cooled at natural
atmospheric environments. However, it is required to know the surface
temperature in these devices. In this study, the cooling of a plate (1 m in
height and 1 m in width) which is oriented vertical, and also 20°- and
45°-inclined from the vertical (downward-facing surface), at the constant heat
flux of 1000 Wm^-2 at atmospheric natural convection conditions is
investigated. The local temperature values at the vertical center of the plate
are calculated using the correlation in Vliet [1]’s experimental study and
computer analyses and compared to those results. The results show that the
surface temperature values of the plate at the inclination angle of 45° are
relatively higher than those of the plate at the vertical state and those of
the 20°-inclined plate.
