Counter-current flooding phenomena in gas-liquid two-phase flow under an electric field - part 2: Theoretical analysis for the non-adiabatic case in a vertical tube

Abstract A counter-current two-phase flow under an applied d.c. electric field has been studied theoretically using potential flow equations and perturbation techniques. Flooding phenomena have been defined with the degree of agitation on the interface of a gas—liquid system in a vertical tube. A flooding correlation has been derived taking account of the applied electric field on the interface. It is found that the electric field enhances the flooding phenomena in such systems. The effect of the tube diameter on the flooding has been studied. The correlation derived in the present study takes either Wallis type or Kutateladze type respectively, depending upon whether the tube size is smaller or larger.
