Abstract
Wrinkled film boiling is a film boiling characterized by the wrinkled vapor-liquid interface and by the noise and vibration that accompany it. Wrinkled film boiling may be encountered when the degree of subcooling is increased. The effects of system pressures, pool dimension, and heating wire on the occurrence of wrinkled film boiling have been investigated experimentally using 1.2 mm Kanthal Al wire, 0.35 and 1.2 mm DSD wires, 0.6 mm W wire, and 1.00 mm Ni-Cr wire etc. in two pools of methanol. Zones in which wrinkled film boiling may occur have been mapped. Decrease in system pressure results in zone of lower heat flux. The minimum degree of subcooling decreases as system pressure decreases, particularly for wires of large diameters. Wrinkled film boiling occurs when pool size and wire length are above certain minima.
