Numerical Investigation of Fuel Mixing, Ignition and Flame Stabilization by A Strut Injector in A Scramjet Combustor

摘要

In this work the simulation of the non-reacting supersonic flow is presented. The main task of the simulation was to prepare the non-reacting solution for the simulation of reacting flow in the second phase of the project. The flow in a scramjet with a strut injector was simulated. The shock system, temperature field and hydrogen distribution are presented subsequently. Preliminary simulations of the reactive flow were realized with the Finite Rate Model, which is included in 'Fluent 5', in order to investigate potential ignition zones. The model does not yet include the turbulence-chemistry interaction but can, nevertheless, be applied successfully for the initial analysis of the ignition process.
