WebAug 2, 1982 · The bubble, slug, annular-slug transition, and annular mist flow regimes were considered. The method can accurately predict within 10% the two-phase pressure drops … WebA multiphase flow regime in pipes in which one fluid moves as small dispersed bubbles through a continuous fluid. The relative velocity of the bubbles depends mainly on the difference in density between the two fluids. Bubble flow normally occurs at low flow rate and low holdup of the bubbly fluid. brother vx520 sewing machine
