Dynamics of Multiphase Flows : Liquid - Particle Suspensions and Droplet Spreading

Raiskinmäki, Pasi Dynamics of multiphase flows: liquid-particle suspensions and droplet spreading Jyväskylä: University of Jyväskylä, 2004, 152 p. (Research report/Department of Physics, University of Jyväskylä, ISSN 0075-465X; 7/2004) ISBN 951-39-1967-6 diss. Most fluids that appear in nature as well in numerous applications in industry are multiphase fluids such as liquid-particle suspensions...

Interfacial Rheology of Gas/Liquid and Liquid/Liquid Interfaces

An interfacial shear rheometer for stressand strain-controlled measurements at liquid interfaces is outlined. Experimental data are reported for the surfactant sorbitan tristearate on κ-carrageenan subphases. A setup combining interfacial rheometry with Brewster-angle Microscopy for realtime imaging of the interface is presented. INTRODUCTION Dynamic processes involving deformable fluid interfa...

Finite element discretization and iterative solution techniques for multiphase flows in gas-liquid reactors

A mathematical model for gas-liquid flows subject to mass transfer and chemical reactions is presented. It is shown that bubble-induced buoyancy resembles natural convection and can readily be incorporated into an incompressible flow solver by using an analog of the Boussinesq approximation. Extra transport equations with nonlinear source terms are introduced to describe the evolution of scalar...
