Abstract

Abstract—Nowadays, dedicated computer programs developed on the basis of finite element analysis and using modern mathematical models of physicochemical processes are widely applied in designing new or optimizing existing devices and installations firing organic fuels. Such multiparametric tasks, which encompass a wide range of physical problems, are predominantly solved by means of CFD modeling based on the finite volume method. This numerical method for integrating systems of differential equations with partial derivatives features versatility and numerical stability. Particular problems that are dealt with by applying computer programs that use CFD modeling are solved in a few sequential stages: preparing the problem for solving, verifying the mathematical model, visualizing the calculated results and preprocessing them, and analyzing the obtained results. The article discusses the experience gained with modeling and suggests the main recommendations on using this software product in engineering practice for solving particular problems concerned with ignition and burnout of gaseous and liquid fuel and emission of harmful combustion products in power installations for developing new or optimizing existing designs of various furnace and burner devices.
