Recent Advances in Kinetic-Based CFD Models for Polydisperse Multiphase Flows
In the framework of Erasmus Mundus “Multiphase”, the Department of Applied Science and Technology-DISAT of Politecnico di Torino promotes a seminar titled "Recent Advances in Kinetic-Based CFD Models for Polydisperse Multiphase Flows".
The seminar will feature with the presence of Rodney O. Fox – Department of Chemical and Biological Engineering, Iowa State University, Ames, Iowa, USA.
Polydisperse multiphase flows arise in many industrial and environmental applications, and almost always involve a disperse phase with particles of different sizes and compositions. Moreover, the disperse-phase volume fraction covers a wide range, even in the same application. In this lecture, Rodney O. Fox will review recent advances in using kinetic-based moment methods to develop well-posed Eulerian-Eulerian CFD models. This approach relies on formulating a kinetic equation for the disperse phase valid from close-packed to dilute conditions, coupled to a modified Navier-Stokes equation for the continuous phase. Through numerous examples, Rodney O. Fox will demonstrate that by including added mass and particle-fluid-particle stresses, this modeling approach is well posed for polydisperse flows with arbitrary material density ratios (i.e., bubbly, liquid-solid and gas-solid flows).
