Abstract:

The presence of the C=C moiety in fuel molecules allow for radical addition reactions to occur which make their combustion feature particularly interesting and different from alkanes. Different types of atoms and radicals can add to the double bond to form the chemically activated intermediates, R*, which can either undergo collisional stabilisation or decompose to form bimolecular products. The significance of this competition between collision and chemical reaction processes is that the formation of stabilised intermediates or bimolecular products becomes dependent on both temperature and pressure. The position of the C=C can influence the reactivity of the fuel significantly. Based on the comprehensive combustion chemistry model of unsaturated C4 species, this talk with reveal the important reaction class changes along temperature and pressure which are specific to unsaturated fuel chemistry.

Bio:

Chongwen Zhou is Professor of School of Energy and Power Engineering at Beihang University, China. Chongwen got her PhD degree in 2009 from Sichuan University, then she moved to National University of Ireland Galway to work with Prof. Henry Curran as a postdoctoral. Since 2015, she also worked in school of chemistry at NUI Galway as an honorary research lecturer until September 2017 she move to Beihang University. Her research aims to shed lights on fundamental computational combustion chemistry of different type of fuels. Her research is composed of two areas: (1) comprehensive computational combustion model development for both fossil and alternative fuels. She and co-authors have developed the comprehensive combustion chemistry model for the unsaturated C4 species and release the AramcoMech 2.0; (2) high-level ab initio calculations for key reactions in those fuel combustion processes. Combining the current high-level ab initio calculations into the combustion modelling development is an efficiency and reliable way to provide accurate combustion chemical models for both “real” fossil and alternative fuels. She has published 26 journal papers and as a referee for journals including Combustion and Flame, Energy & Fuels, Proceeding of Combustion Institute, Journal of Physical Chemistry, Physical Chemistry Chemical Physics, Journal of Computational Chemistry, RSC advance, International Journal of Chemical Kinetics, Molecular Physics etc.
