Numerical Methods for Reacting Gas Flow Simulations

Numerical Methods for Reacting Gas Flow Simulations

In this study, various numerical schemes for transient simulations of 2D laminar reacting gas flows, as typically found in chemical vapor deposition reactors, are proposed and compared. These systems are generally modeled by means of many stiffly coupled elementary gas phase reactions between a large number of reactants and intermediate species. The purpose of this study is to develop robust an...

Implicit Methods for Computing Chemically Reacting Flow

Numerical simulations of glottal flow

Features of glottal flow are visualized by numerical simulation, using a Navier-Stokes solver for two-dimensional, incompressible flow. Four different shapes of glottal passages are examined, for comparison to stationary model measurements. Results include pressure distributions leading to the forces acting on the vocal folds and illustrate entry pressure loss and exit recovery. Flow field imag...
