• Nota di contenuto: Formulation of the premixed and nonpremixed test problems -- Premixed and nonpremixed test problem results -- Reducing mechanisms -- Overview of asymptotics for methane flames -- On reduced mechanisms for methane-air combustion -- Structure of the oxidation layer for stoichiometric and lean methane-air flames -- Asymptotic analysis of methane-air diffusion flames -- Sensitivity analysis of laminar premixed CH4-air flames using full and reduced kinetic mechanisms -- Application of reduced chemical mechanisms for prediction of turbulent nonpremixed methane jet flames -- Conventional asymptotics and computational singular perturbation for simplified kinetics modelling.
• Sommario/riassunto: In this comprehensive text a systematic numerical and analytical treatment of the procedures for reducing complicated systems to a simplified reaction mechanism is presented. The results of applying the ; reduced reaction mechanism to a one-dimensional laminar flame are discussed. A set of premixed and non-premixed methane-air flames with simplified transport and skeletal chemistry are employed as test problems that are used later on to evaluate the results and assumptions in reduced reaction networks. The first four chapters form a short tutorial on the procedures used in formulating the test problems and in reducing reaction mechanisms by applying steady-state and partial-equilibrium approximations. The final six chapters discuss various aspects of the reduced chemistry problem for premixed and nonpremixed combustion.

• Sommario/riassunto: The essentials of point-set topology, complete with motivation and numerous examples Topology: Point-Set and Geometric presents an introduction to topology that begins with the axiomatic definition of a topology on a set, rather than starting with metric spaces or the topology of subsets of Rn. This approach includes many more examples, allowing students to develop more sophisticated intuition and enabling them to learn how to write precise proofs in a brand-new context, which is an invaluable experience for math majors. Along with the standard point-set topology topics-connected and pa
