speckle correlometry

Speckle correlometry as a method for evaluating the dynamics of the liquids foam

Background and Objectives: The two-phase gas-liquid foams have been an active object of research over the past few decades. Usually, during the coarsening of the foam such physical processes as a foam syneresis (the liquid drainage along the Plateau channel and the bubble walls under the gravity), an Oswald ripening of the gas bubbles, and their coalescence are investigated.
