Heat transfer coefficient between an electrically heated 19 0 mm diameter vertical probe and slurries of glass beads of different sizes (50.0, 117.6 and 143.3 I~m) and concentrations (108-312 kg/m 3) is determined in a 10.8 cm diameter bubble column as a function of superficial air velocity (0.103-0

An experimental investigation to clarify the bubble flow and the effects of rising bubbles on boiling heat transfer in tube bundle was conducted by using nitrogen bubble simulation. The experimental results showed that the rising bubbles from the different parts of the lower tube surface have differ
Alrstract--The mechanisms of boiling heat transfer on the outside of a horizontal tube are multifarious and include contributions from site nucleation, micro-layer evaporation and liquid disturbance. Previous work has shown the strong influence of sliding bubbles which disturb the liquid and can lea
