EFFECTS OF BUBBLE SHAPE ASSUMPTION ON SINGLE BUBBLE GROWTH BEHAVIOR IN NUCLEATE POOL BOILING
ABSTRAKT
Analytical research was performed to show the effects of bubble shape assumption on the equivalent bubble radius and heat flow rate behavior during bubble growth, based on experimental results for saturated nucleate pool boiling. The equivalent bubble radius was calculated from bubble images captured during the growth phase using the shape assumption for bubble geometry. The heat flow rate was measured using a microscale heater array and a Wheatstone bridge circuit controller. A theoretical analysis was then performed to illustrate that the form of the bubble shape assumption is very important when analyzing single bubble growth behavior.
