Three-dimensional microscale numerical simulation of smoldering

A three-dimensional numerical tool for the simulation of smoldering in fixed beds of solid fuels is presented in this paper. The description is based on the microscale equations, in a detailed discretized image of the porous medium. Simplifying assumptions are used, but the local coupling of the transport and reaction mechanisms is fully preserved. A set of 2D and 3D simulations demonstrates th...

Numerical Simulation of Three-Dimensional Dendritic Growth.

Dendritic crystal growth in a pure undercooled melt is simulated quantitatively in three dimensions using a phase-field approach. The classic parameter s that characterizes the dynamically selected operating state of the dendrite tip as well as the full nonaxisymmetric tip morphology are determined as a function of anisotropy for a crystal with a cubic symmetry. Results are compared to experime...

Three-dimensional Numerical Simulation of Dough Kneading

In this article we report on work concerned with the three-dimensional numerical simulation of dough mixing that arises in the food processing industry. Two dough mixers at various rotation speeds are studied, one with one stirrer and the other with two stirrers. Various types of fluid models are incorporated in this work. Numerical simulations are based on three dimensions in the cylindrical c...

Numerical Simulation of Pulse Detonation Engine Phenomena

This computational study examines transient, reactive compressible flow phenomena associated with the pulse detonation wave engine. The PDWE is an intermittent combustion engine that relies on unsteady detonation wave propagation for combustion and compression elements of the propulsive cycle. The present computations focus on high order numerical simulations of the generic PDWE configuration w...
