WebMar 24, 2024 · In engineering and physics, multiphase flows describe a variety of problems that involve the combined flow of several phases — gas, liquid or solid. The phases may be clearly separated, e.g. when air blows over ocean water and generates waves. The phases may also mix, e.g. when waves break to form a foam of water and air bubbles.
