THE LEVICH INSTITUTE ANNOUNCES THE FOLLOWING SEMINAR

Tuesday, 09/19/2000 4:00 PM Steinman Hall, Room #1M-22 Professor Lian-Ping Wang Mechanical Engineering Department University of Delaware "Simulation and Modeling of Turbulent Collision of Inertial Particles"

ABSTRACT

I will present an overview of recent advances towards a better understanding of inertial effects on the coagulation process of drops and particles within a turbulent flow. Using direct numerical simulations as a quantitative research tool, we have resolved a number of open issues in the modeling of turbulent coagulation. Specifically, we will discuss a statistical mechanical description of collision rates for inertial particles and how it can be used to develop an accurate coagulation model, when particles are nonuniformly distributed as a result of the preferential concentration effect. Effects of particle settling and local hydrodynamic interactions will also be discussed.
