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...
متن کاملBubble formation on a single orifice in a gas solid fluidized bed using digital image analysis
Digital Image Analysis (DIA) has been employed to characterize the time evolution of a bubble injected from a single orifice into a pseudo 2-dimansional gas-solid fluidized bed. The injected bubble diameter increased with the square root of time before detachment. During bubble free flight in the bed, its diameter remains approximately constant. The center of mass of the bubble increases with t...
متن کاملTheoretical and Experimental Bubble Formation at a Single Orifice in a Two-dimensional Gas-fluidized Bed
An earlier developed, first principles hydrodynamic model of gas-fluidized beds has been employed to study theoretically bubble formation at a single orifice in a two-dimensional bed. For several orifice discharge rates, theoretically predicted bubble sizes, formation times and shapes have been compared with experimental data obtained from triggered photographs. Besides, the present experimenta...
