Abstract

IN THIS RESEARCH THE GAS AND LIQUID PHASES OF A BUBBLE COLUMN WERE MODELED IN A THREE-DIMENSIONAL IN THE EULERIAN FRAMEWORK BY USING COMPUTATIONAL FLUID DYNAMIC. THE SIMULATIONS HAS BEEN DONE IN A BUBBLE COLUMN WITH FIVE HEATER FOR THE PITCH TO DIAMETER RATIOS OF 1.5, 2 AND 2.5. EULERIAN-EULERIAN MULTIPHASE WITH K-E TURBULENCE MODLE WERE USED FOR THE SIMULATIONS. THE SIMULATIONS HAS BEEN DONE FOR SUPERFICIAL GAS VELOCITIES IN THE RANGE OF 0.0025 TO 0.04 M/S IN A BUBBLE COLUMN WITH 0.292 M IN DIAMETER AND 1.5 M IN HEIGHT. THE REASULTS SHOW THAT, WITH INCREASING SUPERFICIAL GAS VELOCITY THE GAS HOLDUP INCREASES. AT A CONSTANT SUPERFICIAL GAS VELOCITY, WITH INCREASING THE PITCH TO DIAMETER RATIO FROM 1.5 TO 2.5 THE GAS HOLDUP INCREASES. RADIAL DISTRIBUTION OF GAS HOLDUP AND RADIAL DISTRIBUTION OF WATER VELOCITY HAS BEEN REPORTED TOO.
