Download or read book Implicit Multigrid Method for Modeling 3-D Laminar Diffusion Flames with NOx Prediction written by Chaoqun Liu and published by . This book was released on 1994 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: An implicit multigrid time-stepping technique is applied to the laminar diffusion methane-air combustion with detailed description of NOx formation in a 3-D channel. The chemical reaction model is assumed to have 48 species and 229 finite-rate, reversible reaction steps. The computation requires about 90 time steps to reduce the residual by 3 orders of magnitude on a 34 x 18 x 18 grid.
