Presentation Transcript

  1. Poster Presentation Session CREL Annual Meeting November 2001 CREL meeting, 15th November 2001

  2. CHEMICAL REACTION ENGINEERING LABORATORY Posters presented by Peter Spicka Hydrodynamics of 2D Gas-Liquid Reactors: Experimental Study and CFD Simulations Laboratory of Separation and Reaction EngineeringDepartment of Chemical Engineering, University of Porto Experimental Characterization of Gas-Liquid Column: Effect of Nozzle Orientation and Pressure CREL meeting, 15th November 2001

  3. Peter Spicka Education 1994 Eng. degree at Slovak Technical University in Bratislava 2001 PhD degree at University of Porto Participation on European project ADMIRE CREL joined in April 2001 • Research Focus • CARPT, CT experiments in multiphase columns • Trickle bed reactors filled with structured packing • CFD simulations - turbulence modeling, pressure effect • Experimental study 2D gas-liquid column, effect of structured packing, LDV, PIV, Imaging • CFD simulations effect of lift forces and turbulence on phase distribution CREL meeting, 15th November 2001

  4. 2D Gas-Liquid Column Experiment & Simulations LDV data Experimental techniques • Pressure transducers • Imaging • BIV • LDV Simulations CFD simulations • Study of lift forces • Turbulence models Euler/Euler Model • No mass transfer • Uniform bubble size • Neglected interfacial pressure drop Column dimensions (600  200 2) mm Packing Placed in diamond shaped structure at porosity = 0.6 CREL meeting, 15th November 2001

  5. Experiment 6” stainless steel column Cross-sparger, two nozzle orientations: facing upward and downward Air-water system Pressure: 1 bar and 4 bars UGS= 5 cm/s (only CT) and 20 cm/s CT & CARPT Results Effect of Pressure and Nozzle Orientation • Objective • Study the sparger nozzle orientation effect on gas hold-up, liquid velocity and turbulence in gas-liquid column Gas Holdup Turbulent kinetic energy CREL meeting, 15th November 2001
