Numerical Simulation for Turbulent Combustion in Underwater Vehicle Combustor

Numerical Simulation of Premixed Turbulent Methane Combustion

In this paper we study turbulent premixed methane flames with swirl using three-dimensional numerical simulation. The simulations are performed using an adaptive time-dependent low Mach number combustion algorithm based on a second-order projection formulation that conserves both species mass and total enthalpy. The species and enthalpy equations are treated using an operator-split approach tha...

Large-eddy simulation analysis of turbulent combustion in a gas turbine engine combustor

Direct Numerical Simulation of Sprays: Turbulent Dispersion, Evaporation and Combustion

Numerical procedures to describe the dispersion, evaporation and combustion of a polydisperse liquid fuel in a turbulent oxidizer are presented. Direct Numerical Simulation (DNS) allows one to describe accurately the evolution of the fully compressible gas-phase coupled with a Lagrangian description in order to describe two-phase flows. Standard coupling is used for the Eulerian/Lagrangian syst...

Turbulent Combustion Simulation by Large Eddy Simulation and Direct Numerical Simulation

Combustion is a natural phenomenon. It happens in forest, automotive engine and gas cooker. In Computational Fluid Dynamics (CFD), the combustion phenomenon complies with a set of partial differential equations. According to the resolution scale, from big to small, the simulation methods in combustion are Reynolds Averaged Navior Stokes method (RANS), Large Eddy Simulation (LES), and Direct Num...

Performance of a direct numerical simulation solver for turbulent combustion on the Cray XT3/XT4

Parallel performance of a flow solver, S3D, for direct numerical simulation of turbulent combustion is evaluated on the latest Cray XT system installed at the National Center for Computational Sciences (NCCS). S3D is a massively parallel code that uses MPI for message passing parallelism. It has been ported to various platforms at the Office of Science computational facilities and scales very w...
