Natural, mixed and forced convection liquid cooling of
discrete heat sources in a vertical channel were investigated
experimentally. Ten heat sources were flush mounted to one
wall of a water filled channel, while the opposite wall was
unheated. Measurements of heater surface temperatures were
made for a channel Reynolds number range of - 17 00 and heat
flux range of 1050 - 4500 W/m2
. In the mixed convection
regime, both aiding and opposed flow were examined.
Temperature patterns on the heated surface were visualized
using liquid crystals.
