Large Eddy simulation (LES) models are presented and evaluated on a database obtained from Direct Numerical Simulation (DNS) of a three-dimensional temporal mixing layer with evaporating drops.
Large Eddy Simulation (LES) is conducted of a three-dimensional temporal mixing layer whose stream is initially laden with liquid drops which may evaporate during the simulation. The gas-phase equations are written in Eulerian frame for two perfect gas species (carrier gas and vapor emanating from the drops), while the liquid-phase equations are written in a Lagrangian frame.
Direct Numerical Simulation is conducted of a three-dimensional temporal mixing layer whose lower stream is initially laden with liquid drops which may evaporate during the simulation.
Large eddy simulation models are presented and evaluated on a database obtained from direct numerical simulation of a three-dimensional temporal mixing layer with evaporating drops.
Large Eddy Simulation (LES) models are evaluated on a Direct Numerical Simulation (DNS) database representing a three-dimensional temporal mixing layer with evaporating drops.
Analysis of Direct Numerical Simulations (DNS) transitional states of temporal, supercritical mixing layers for C7H16/N2 and O2/H2 shows that the evolution of all layers is characterized by the formation of high-density-gradient magnitude (HDGM) regions.
A derivation of the irreversible entropy production, that is the dissipation, in two-phase flows is presented for the purpose of examining the effect of evaporative-drop modulation of flows having turbulent features.
