Movies: Nucleate boiling in the low gravity environment of the KC-135 aircraft.

Single Bubble
Fluid: Saturated water
Gravity: 0.01g

Two Bubble Merger
Fluid: Saturated water
Gravity: 0.01g

Three Bubble Merger
Fluid: Saturated water
Gravity: 0.01g

Movies: Numerical simulation of boiling.

1) Single Bubble-Vertical merger

Fluid: Saturated water, earth normal gravity, wall superheat = 7 K, contact angle = 38.

2) Five Bubble Merger

Fluid: Saturated water, earth normal gravity, wall superheat = 7 K, contact angle = 54, spacing between cavities = 0.6 mm

3) Five Bubble Merger

Fluid: Saturated PF5060, low gravity g = 0.00001ge, wall superheat = 7 K, contact angle = 10, spacing between cavities = 20 mm, waiting time = 0.5 sec
