Study on the Effective Parameters for the Geysering Period

Experimental investigation of effective parameters on geyser periodicity in a vertical heated system

“…These results clearly indicate that the geyser boiling occurs more frequently at a higher heat load. It is consistent with the phenomenon depicted by Lin et al [18], Tae-il et al [36] and Chen et al [26] but different from what Ozawa et al [19] observed that the period increased with the heat flux density. And these completely different results may be explained by the employed forced flow boiling system and the vertical closed system without circulation which has dominated different heat transfer modes in the flow channel.…”

“…Burkhalter et al [21] concentrated on influence of three variables, i.e., reservoir fluid temperature, heating rate, and length/diameter ratio on the geysering mechanism. It was shown that the geysering period increased in a linear fashion as reservoir fluid temperature decreased, which was opposite to the conclusions made by Tae-il et al [20]. It was also found that the geyser intensity increased until the system ceased to geyser as heating rate was decreased.…”

“…The amplitude of geysering increased with an increase in the heat flux density and the riser length, and a decrease in the inlet velocity. Tae-il et al [20] experimentally and numerically investigated effective parameters on the geysering period using a bottom closed vertical tube. It was found that the geysering period decreased as the heat flow rate and subcooled temperature in the expansion tank increased.…”

Fundamentals of Multiphase Flow

“…The dependence of the geysering period on the strength of the heat source and on the temperature of the sub-cooled water in the water supply is exemplified in figure 15.7 which presents results from the small scale laboratory experiments of Tae-il et al (1993). That figure includes both the experimental data and the results of a numerical simulation.…”
