  5. NTNU Department of Chemical Engineering • Objectives • The main goals of the program are to develop new physical models for fluid flow computations, particularly focused on models applicable to design and optimization of chemical and metallurgical processes, and to strengthen the academic education and research in these fields at NTNU and SINTEF by: • Graduating a minimum of 5 doctorates within these fields and strengthen the collaboration with international research groups through exchange on doctoral and post doc. level. • Developing model programs and experimental validation tools for a selection of specific applications. • Establish a graduate course in advanced reactor technology and multiphase flow. • Strengthen the links between the fundamental and applied research, and the Norwegian industry.

  7. The CARPET Project – Dissemination of information • We aim at publishing a minimum of 25-30 papers and contributions in refereed journals and at national andinternational conferences. • We will arrange semi-annual seminars where the dr.ing fellows and researchers will present their work for invited industrial partners and other interested parties. • Close collaboration with the NFR- and industry supported programme HiPGaS will be maintained (see www.hipgas.ntnu.no).

  8. The CARPET Project – Results? Improved Knowlege on: • Multiphase Flow Modeling (bubbles/particles - Stratified) • Population Balance Modeling (coalescence/breakup) • Turbulence Modeling (single- and multiphase Flow, LES) • Granular Flow Modeling • Numerical Schemes (Convection, Interface, Cut-Cells, LB) • Simulation and Validation of Stirred Tanks (Stirrer/Heat) • Experimental Techniques (Fluid Particles, Interface, bulk) • Discrete Element Method (DEM) • Project Administration!
