In 20-foot ISO containers, several experiments have been conducted to provide data for combustion model improvement and validation. The first experimental campaign included a blindprediction study concerning two lean premixed configurations. The hydrogen research group of IKET submitted a model prediction based on the in-house code COM3D. The experimental results were not matched. Therefore, the objective of this thesis was to improve the predictability of the CFD code by carrying out post-blind simulations. Over the course of this work, the roles of thermodiffusive instability and the turbulent flame speed model in the process of flame acceleration were analyzed and clarified. As a consequence, the numerical model for the transition from laminar to turbulent flame speed was developed and implemented in the COM3D code. Validating simulations demonstrated satisfactory agreement compared to the experimental results. This represents a first step toward extending the applicability of the code to a wider range of combustion scenarios." "Das EU-Projekt HySEA widmet sich der Verminderung von Explosionsrisiken durch Deflagrationsentlüftung industrieller Wasserstoff-Anlagen. Zur Weiterentwicklung und Validierung von Verbrennungsmodellen wurden verschiedene Experimente in 20-Fuß ISO Containern durchgeführt. Die erste Testkampagne beinhaltete die Blindvorhersage von zwei mageren vorgemischten Versuchsanordnungen. Die Wasserstoff-Gruppe des IKET reichte auf der Basis des institutseigenen COM3D Codes eine Modellvorhersage ein, welche keine zufriedenstellende Übereinstimmung mit den Experimenten zeigte. Das Ziel dieser Arbeit war daher, die Vorhersagbarkeit des CFD Codes anhand nachgelagerter Berechnungen zu verbessern. Im Hinblick auf den Prozess der Flammenbeschleunigung wurden insbesondere die Rolle thermodiffusiver Instabilität und das Modell turbulenter Flammengeschwindigkeit analysiert und geklärt. Daraus folgte die Weiterentwicklung des numerischen Modells des Übergangs von laminarer zu turbulenter Flammengeschwindigkeit sowie dessen Implementierung in den COM3D Code. Validierungsrechnungen zeigten erfolgreiche Übereinstimmung mit den experimentellen Ergebnissen. Dies stellt einen ersten Schritt zur Erweiterung des Anwendungsspektrums des Codes für weitere Verbrennungsszenarien dar."
