Abstract:

A review is presented of methods of modeling interfaces in numerical simulations. Interface capturing methods, in which the finest scales of the interface are resolved, and interface tracking approaches methods, in which the interface is treated as a discontinuity are discussed. Interface tracking approaches include moving-grid methods, surface tracking methods, volume tracking methods, and gradient methods. Keywords Interface tracking Reactive flows.
