Colloid Colloid In chemistry, a colloid is a mixture in which one substance of microscopically dispersed insoluble particles is suspended throughout another substance. Sometimes the dispersed substance alone is called the colloid; the term colloidal suspension refers unambiguously to the overall mixture (although a narrower sense of the word "suspension" is distinguished from colloids by larger particle size). Unlike a solution, whose solute and solvent constitute only one phase, a colloid has a dispersed phase (the suspended particles) and a continuous phase (the medium of suspension). To qualify as a colloid, the mixture must be one that does not settle or
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.
