Geysering effect

WebApr 1, 2024 · The effect of aspect ratio on geyser is thoroughly investigated for two different changing ways and then the performance of Murphy curve is assessed. The results indicate that the flow and boiling regime in a bottom closed cryogenic pipe could be divided into four types, namely natural convection, stable boiling, weak geyser, and strong geyser. WebJun 1, 1983 · In fact, the geyser effect has a cyclical character and may be described as occurring in three phases: (I) Surface evaporation with natural convection coupled with a heating of the liquid in the pool. (2)The sudden development of bubbles with some of the liquid propelled towards the condenser. Cl E I7 I 1 50 57 64 71 'C FIG . 5.
