OD Simulation of NH 3 Combustion Based on Reaction Kinetics
Simulation 0D de la combustion NH3 basée sur la Cinétique de Réactions
Résumé
Ammonia is being taken more and more seriously as an energy carrier for large marine vessels and off-highway use from year to year. Especially applications with high demands for power and energy density can profit from the use of an ICE rather than fuel cells or purely electric power storage. For an efficient application of ammonia in combustion engines, more basic mixing and combustion phenomena have yet to be understood and looked at with test bench measurements. However, for a later adoption of existing engine designs or the adoption of new engine models to ammonia combustion, simulation is equally needed. It helps to front load the design processes and is critical for an efficient dimensioning of the engine components and peripherals. To allow this, the intrinsic fuel properties of ammonia have to be gathered and processed in a way that they can be easily accessed by the simulation environment. Some of those properties, like the lower heating value or the stoichio-metric air requirement are easy to implement. Others require reaction kinetic calculations and more effort to efficiently store and access – especially the laminar burning velocities and ignition delay times need extensive attention. For this, an automated methodology that acquires and stores up to 20 relevant fuel properties for pure fuels and especially fuel mixtures has been developed and presented in [1]. The aim of this work is to vali-date the already established process for its application in ammonia combustion
