This research describes the unsteady two-dimensional reacting flows around a circular cylinder. The numerical solution combines the random vortex method for incompressible two-dimensional viscous fluid flow with a Simple Line Interface Calculation (SLIC) algorithm for the propagation of flame interface. To simplify the governing equations, two fundamental assumptions namely Low Mach Number and ...

Submitted for the DFD13 Meeting of The American Physical Society Axial Evolution of Helical Modes in Reacting Swirl Flow MIKE AGUILAR, BENJAMIN EMERSON, DAVID NOBLE, TIM LIEUWEN, Georgia Institute of Technology — The swirling jet is a common method of flame stabilization for ground power and aviation combustors. The hydrodynamic stability characteristics of high Reynolds number, reacting, swirl...

Abstract: We investigate a prototype concept of a back-up electricity device where we use liquid formic acid (FA) to produce a mixture of carbon dioxide (CO2) and hydrogen (H2) which is used in a PEM fuel cell, Fig. 1. In the fluidized bed reactor the liquid FA is decomposed to a gaseous mixture of CO2 and H2 in the presence of microscopic floating solid catalytic particles. We describe the sys...

Uniform regularity plays an important role in the global existence of strong solutions and large time behavior solutions. In this work, we prove uniform smooth to compressible flow a chemically reacting gaseous mixture $\mathbb{T}^3$.

This article presents molecular-level analysis of a reactive, near-continuum, Mach 21 nitrogen flow over blunt wedge using the direct molecular simulation (DMS) method. The conditions lead to internal energy excitation and dissociation in field, resulting thermal chemical nonequilibrium flow. Thermal vibrational mode is observed extend level, where distributions at various points field are be n...

In this chapter the method of lines is applied to computational models of reacting flow arising from atmospheric applications. These computational models describe the chemical transformations and transport of species in the troposphere and have an essential role in understanding the complex processes which lead to the formation of pollutants such as greenhouse gases, acid rain and photochemical...
