Direct Numerical Simulation of Turbulence in a Model Solid Rocket Motor
The direct numerical simulation database is also used to make a priori estimates of the relative magnitudes of subgrid terms in the filtered evolution equations. It is found that in the equations for mean momentum and resolved scale Reynolds stress, the dominant subgrid terms are the subgrid stress …

Closure Modeling for Accelerated Multiscale Evolution of a 1-Dimensional Turbulence Model
Accelerating the simulation of turbulence to stationarity is a critical challenge in various engineering applications. This study presents an innovative equation-free multiscale approach combined with a machine learning technique to address this challenge in the context of the one-dimensional …

Methods Development and Validation for Large Scale Simulations of Dense Particulate Flow systems in CFD-DEM Framework
… is widely used in simulating a large variety of particulate flow system. This Eulerian-Lagrangian technique tracks all the particles included in the system by the application of point mass models in their equation of motion. CFD-DEM is a more accurate (and more expensive) technique compared to …

High order numerical methods applied to the analysis of transport phenomena in combustion
… numerical methods present the desirable property of having much less error than second order methods for the same number of nodes, or degrees of freedom. This makes them very attractive for applications like computational acoustics and aeroacoustics, prediction of transition or direct numerical …
