Homogeneous and heterogeneous mixtures mixture is air. In physical chemistry and materials science this refers to substances and mixtures which are in a single phase. This is in contrast to a substance that is heterogeneous. A solution has been a special type of homogeneous mixture. Solutions are homogeneous because the ratio of solute to solvent remains the same throughout the solution even if homogenized with multiple sources, and stable because the solute will not settle out after any period of time, and it cannot be removed by a filter or by centrifuge. This type of mixture is very stable, i.e., its particles do not
Cavitation modelling on the bubbles. Discrete bubble models, e.g. the Rayleigh-Plesset, Gilmore and Keller-Miksis, describe the relation between the external pressure, bubble radius and the velocity and acceleration of the bubble wall. Two-phase modeling is the modelling of the two phases, as in a free surface code. Two common types of two phase models are "homogeneous mixture models" and "sharp interface models". The difference between both the models is in the treatment of the contents of cells containing both phases. Most recent cavitation modelling efforts have used homogeneous mixture models, in which the contents of individual cells are assumed to be uniform.
