Simulation komplexer fluider Transportvorgänge in der Verfahrenstechnik

Simulation of Complex Liquid Transport Processes in Chemical Engineering The numerical calculation of flows has become a universal tool in several scientific and technical applications to be able to better understand or control the transport processes in fluids. Still, in many areas of chemical engineering technology the use of numerical simulations is less developed. One of the reasons for this is the low reliability and efficiency of standard CFD techniques. How can simulation methods in combination with alternative grid generation techniques be used to generate reliable predictions of the operation behavior relation of components in the chemical industry? A new way is demonstrated here, whereby the described calculation techniques are based on one of the most rigorous models of the transport processes of fluids, namely the Boltzmann equation.     

CFD‐Simulation und LDA‐Messung der Strömungsvorgänge beim Fluidphasenresonanzmischen

The principle of fluid phase resonance mixing is to apply harmonic oscillating pressure via a gas cushion on a liquid phase in a vessel and thus to cause the liquid phase to start oscillating. This principle is simulated as an unsteady flow of two separate phases with open source CFD software OpenFOAM and the results are verified with measurements by Laser Doppler Anemometry.
