Multiphase flows are used in a variety of applications, such as protein (adsorptive) separation by high-gradient magnetic separation to specifically extract fermentation products from by-products. This method is based on adsorption processes in which the adsorptive binds to the functionalized surface of magnetic carrier particles. The separation step is carried out by magnetic forces, after that the elution takes place. In order to get a better insight into the whole process, the behaviour of the magnetic particles and the liquids (water, adsorptive) is investigated, mainly by simulation.
