Background and objectives:
Design and operation of modern gas turbine engines faces the need to combine high efficiency with low pollutants emissions. At the same time, safe design and operation of such engines as well as, more generally, of any industrial chemical plants where flammable substances are stored, handled, processed or produced, requires prevention of unwanted combustion phenomena, such as explosions, and/or mitigation of their consequences. This course addresses both subjects in the perspective of Computational Fluid Dynamics. CFD has become a powerful tool in design and analysis of aero engines as well as land based and marine turbines. In addition, it is becoming one of the most important tools for investigating explosion scenarios.
Many numerical models exist, each having a range of applicability, computational cost and accuracy. Consequently, CFD experts involved in combustion engine and explosion simulations, in addition to usual CFD skills, need specific insight and knowledge in multi-phase flow and combustion modelling in order to conduct thorough analysis.
In this course, the participants will learn the best practices in CFD of gas turbine combustors and explosions. They will discover how to select models, how to validate numerical simulations, and which accuracy to expect. A major part of the course is devoted to the main critical issues in the design of modern gas turbine engines (such as spray injection, flame ignition, flame propagation, pollutants emissions, efficiency, including complex alternative fuels) and simulation of explosions (such as dispersion and mixing of reactants, unsteady flame propagation in closed vessel, transient flame-vortex interaction, flame acceleration, pressure evolution).
The lectures of this course, all by well-known experts in the field, cover from basics to applications.
The course is partially based on the ERCOFTAC Best Practice Guide on CFD of combustion, a copy of which will be provided to the participants.In the course, also the link will be made with the CFD programs and cases of interest for the participants. As a result, the course provides the means for CFD analysts to significantly enhance their use of commercial and open-source CFD software for combustion engineering applications.
