...Rishi Raj; Jungho Kim; John McQuillen A framework for scaling pool boiling heat flux is developed using data from various heater sizes over a range of gravity levels. Boiling is buoyancy dominated for large heaters and/or high gravity conditions and the heat flux is heater size independent...

...Rishi Raj; Jungho Kim A pool boiling regime map demarcating the boundary between the surface tension and buoyancy dominated boiling regimes is developed based on heater size and gravity. For large heaters and/or high gravity conditions, boiling is dominated by buoyancy, and the ebullition cycle...

... range of gravity levels ( 0 g – 1.8 g ) under subcooled liquid conditions ( n -perfluorohexane, Δ T sub = 26 ° C , and 1 atm), two gas concentrations (220 ppm and 1216 ppm), and three heater sizes (full heater- 7 × 7 mm 2 , half heater- 7 × 3.5 mm 2 , and quarter heater- 3.5 × 3.5 mm 2 ). As the gravity...
