Model of fractionation and coalescence of gas bubbles in a turbulent liquid flow

A system of equations for describing the evolution of the size range of gas bubbles as a result of their fractionation and coalescence in an isotropic turbulent decaying flow of incompressible liquid is derived and solved numerically. Outer parameters are found by which one can effectively control t...

Zusammenfassung:A system of equations for describing the evolution of the size range of gas bubbles as a result of their fractionation and coalescence in an isotropic turbulent decaying flow of incompressible liquid is derived and solved numerically. Outer parameters are found by which one can effectively control the probability distribution of the bubble radii. [PUBLICATION ABSTRACT]
