Challenges in Modeling Ammonia Combustion Using Methodologies Originally Designed for Hydrocarbons - Seminario

Dettagli

Lunedì 22 Giugno 2026 alle ore 10, nell'Aula Magna del Polo di Ingegneria, il Prof. Cosmin Dumitrescu (West Virginia University, USA) terrà un seminario dal titolo "Challenges in Modeling Ammonia Combustion Using Methodologies Originally Designed for Hydrocarbons".

The seminar will also include an overview of ongoing research at WVU on zero-carbon fuels and internal combustion engines, and available opportunities for thesis projects or student exchanges in these fields.

Abstract

Dr. Cosmin Dumitrescu will discuss the research performed at West Virginia University towards the development of a 0D framework capable of predicting nitrogen-based emissions when NH3 is used as fuel, neat or blended with another fuel. The model is built upon the SI Engine Zonal Simulator (SI EZS) in ANSYS Chemkin-Pro and extends its simplified flame-sheet representation by integrating additional reactors into a multi-stage reactor network. This configuration enables the modeling of detailed combustion and post-combustion kinetics, including reactions of unburned mixture released from crevices and during exhaust processes, while maintaining the low computational cost of the original SI EZS framework. The proposed approach allows the analysis of key reaction pathways influencing NH3 consumption and nitrogen-based emissions and supports rapid evaluation of engine operating strategies such as equivalence ratio, spark timing, and engine speed.
