Bubble formation at multiple ori&ces—bubbling synchronicity and frequency
نویسندگان
چکیده
Bubble formation at two, three, four and six symmetrical ori&ces has been investigated by high-speed photography and analysis of chamber pressure 6uctuations. Regimes of synchronous, alternative and unsteady bubbling were clearly identi&ed, and the e7ects of ori&ce spacing and liquid depth on bubbling synchronicity and frequency were studied. Theoretical predictions of bubble frequency and average radius were found to be in good agreement with experimental data when the bubble regime was highly synchronous. ? 2003 Elsevier Ltd.

A model for bubble formation and weeping at a submerged ori%ce with liquid cross-(ow
A new theoretical model to predict bubble frequencies and weeping rates at a submerged ori%ce with liquid cross-(ow has been developed. The model predicts a signi%cant in(uence of liquid cross-(ow velocity on bubble formation frequency, and especially on liquid weeping. Simulated values of weeping rates for di7erent ori%ce diameters, gas (owrates and liquid cross-(ow velocities show good agreem...
متن کاملA model for bubble formation and weeping at a submerged ori"ce
A theoretical model for bubble formation and weeping has been developed. Potential #ow theory is used to describe bubble formation at the ori"ce. The in#uence of detached, rising bubbles on liquid pressure at the ori"ce is predicted by Oseen's modi"cation to potential #ow. Model predictions of bubble volumes, weeping #ow rates and weep points agree well with experimental results. ( 2000 Elsevie...

A non-spherical model for bubble formation at an ori"ce with liquid cross-#ow has been developed. The interface element approach is applied to describe the dynamics of bubble formation. The e!ect of liquid cross-#ow on the bubble formation process is modelled by a combination of tilting of the bubble axis and liquid pressure analysis of each element on the bubble interface. Model predictions co...
متن کاملA method for bubble volume measurement under constant flow conditions in gas–liquid two-phase flow
Measuring the volume of a bubble, especially at its detachment, is a basic subject in gas-liquid two-phase flow research. A new indirect method for this measurement under constant flow conditions is presented. An electronic device is designed and constructed based on laser beam intensity. This device calculates the frequency of the bubble formation by measuring the total time of the formation p...
متن کاملMechanism and Prevention of Scale Formation in Boilers
Nucleate boiling heat transfer coefficients may be strongly reduced by scale formation, even for conditions where the bulk foulant concentration is well below the saturation concentration. Due to the mechanism of micro-layer evaporation, the local concentration at the heat transfer surface can be considerably increased, causing the formation of scale and changes in bubble frequency and bubble d...
