| description | Saturated partial pool boiling heat transfer has been experimentally
investigated on a horizontal rod heater. The boiling liquids are including
water and ethanol. The heating section is made by various materials including
SS316, copper, aluminum and brass. Experiments have been performed at several
degrees of surface roughness ranging between 30 and 360 micrometer average
vertical deviation. The measurements are including boiling heat transfer
coefficient, bubble departing diameter and frequency and also nucleation site
density. The data have been compared to major existing correlations. It is
shown that experimental data do not match with major correlations at the
entire range of experiments with acceptable accuracy. In this article, the
boiling heat transfer area has been divided in two complementary areas, the
induced forced convection area and the boiling affected area. Based on two
dimensionless groups, including Eötvös and Roshko numbers, a semi-empirical
model have been proposed to predict the boiling heat transfer coefficient. It
is shown that the proposed model provides improved performance in prediction
of the boiling heat transfer coefficient in comparison with to existing
correlations. |
