“…It seems to be natural to derive a Poisson pressure equation from the momentum (Navier-Stokes) equations. The mass conservation equation can be used to simplify it, resulting in Cartesian coordinates (Ferziger and Perić, 1999;de Bortoli, 2003) ( )…”

The present work develops a low cost numerical method for the solution of nonpremixed piloted methane jet flames. This method is based on the mixture fraction for fluid flow and on unsteady flamelet models, combined with the presumed probability density function, for the chemistry. Numerical tests, for the governing equations discretized by the finite difference and solved by the Gauss-Seidel scheme, were carried out for turbulent, nonpremixed, nonreacting propane-jet flow and for confined Sandia C and D flames for reasonable values of gaseous hydrocarbon chemistry. The methodology, developed for low Mach number flows and based on a density approximation, allows to decrease considerably the computational time while obtaining results which contributes to a better understanding of the complexity involved in the numerical solution of piloted methane jet diffusion flames.

“…Among them, flame-vortex interaction has been the subject of many numerical studies. For example, Bortoli [28] studied the numerical solution of laminar flows inside a square cavity caused by a temperature increase due to a chemical reaction. They used the second-order finite-difference spatial and the explicit RungeKutta three-stage temporal schemes to discretize the governing equations.…”

This study reports the results on a numerical investigation of the depollution of smokes produced by the incineration of household wastes in a cylindrical furnace. Transfers are described by double-diffusive mixed convection equations, associated to radiative transfer equation, and a global kinetics model. The governing equations are discretized using finite volume method and the resulting algebraic equations are solved by THOMAS algorithm. The linkage between the pressure and velocity fields is assumed by SIMPLE algorithm. Results are presented as streamlines, isotherms, isoconcentrations for different Reynolds number (300 ≤ Re ≤ 1800). Effects of Reynolds number, relative height opening, aspect ratio, excess air ratio, and radiative transfers on gas pollutants (CO, CH4, C2H4…) destruction are investigated in detail.
