Experimental and numerical simulation of interphase mass transfer of gas bubble in granular backfill and gel

An experimental and numerical study of the process of interphase mass transfer has been performed upon the motion of gas bubble in the granular layer saturated with liquid at different tilt angles of the tube and in the case of movement in the channel between the gel layers. The dependences of the c...

Description
Summary:An experimental and numerical study of the process of interphase mass transfer has been performed upon the motion of gas bubble in the granular layer saturated with liquid at different tilt angles of the tube and in the case of movement in the channel between the gel layers. The dependences of the coefficient of effective dimensionless mass transfer have been obtained depending on the tilt angle of the tube and backfill diameter. The relationship between the coefficient of effective dimensionless mass transfer and the rate of the free-floating gas bubble has been established.
