Large-Eddy Simulation for Particle Collision Growth in Turbulent Flows

Large Eddy Simulation for Turbulent Flows

This thesis is concerned with one of the most promising approaches to the numerical simulation of turbulent flows, the Large Eddy Simulation (LES) in which the large scales of the flow are calculated directly, while the interactions with the small scales are modeled. Specifically, we analyze two new LES models, introduced in [30] and [51]. First, we sketch the derivation of the LES model introd...

Large-Eddy Simulation of Turbulent Reacting Flows

Numerical simulations of combustion in aircraft engines is quite complex, as it requires an adequate description of liquid fuel injection, liquid fuel atomization, drop breakup, drop dynamics, and evaporation, large-scale turbulent fuel air mixing, small scale molecular fuel air mixing, chemical reactions, and turbulence/chemistry interactions. In the present paper, we have identified three of ...
