Computation of combusting flows usi8ng unstructured solution-adaptive meshes

摘要

This paper presents a finite-volume scheme for multidimensional reacting fluid flows. Unstructured solutionadaptive meshes are used, with a cell-centered formulation. The SIMPLE algorithm is used for pressure-velocity coupling. Schemes for hanging-node and conformal adaption are presented. For combustion modeling, the eddy-breakup, and assumed-shape probability density function (PDF) models are implemented in the unstructured-mesh context. The methodology is applied to two benchmark problems; reasonable agreement with experimental measurements is found.
