Bubble behavior in a taylor vortex
WebJul 1, 2024 · Volumetric liquid side mass transfer, bubble size distribution, and bubble shape were measured in a vertically oriented semi-batch gas-liquid Taylor-Couette vortex reactor with an aspect ratio of Γ = h/(r o − r i) = 40 and radius ratio of η = r i /r o = 0.75. Azimuthal Reynolds number, Axial Reynolds number and Capillary number were varied … WebDec 31, 2004 · We present an experimental study on the behavior of bubbles captured in a Taylor vortex. The gap between a rotating inner cylinder and a stationary outer cylinder is filled with a Newtonian mineral oil. Beyond a critical rotation speed (ω[subscript c]), Taylor vortices appear in this system.
