چکیده

We developed a method that will enable us to determine mass transfer coefficients for a large number of two phase flow conditions based on numerical simulation. A three-dimensional direct numerical simulation based on the Front Tracking technique taking into account the mass transfer process was chosen for this purpose. The dissolved species concentration in the liquid phase is tracked using a scalar mass balance while the value of the concentration at the interface is determined via an immersed boundary technique. In the present study, simulations are carried out to investigate the effect of the bubble shape on the dissolved species concentration field.

Effects of coupling on turbulent gas-particle boundary layer flows at borderline volume fractions using kinetic theory

This study is concerned with the prediction of particles’ velocity in a dilute turbulent gas-solidboundary layer flow using a fully Eulerian two-fluid model. The closures required for equationsdescribing the particulate phase are derived from the kinetic theory of granular flows. Gas phaseturbulence is modeled by one-equation model and solid phase turbulence by MLH theory. Resultsof one-way and...
