主讲简介：1999年博士毕业于西班牙瓦伦西亚理工大学工业工程专业，现为瓦伦西亚理工大学CMT研究所所长。其研究工作主要涉及热力机械的燃油喷射、喷雾和燃烧领域。2010年以来，Payri教授主持参与欧盟、西班牙政府科研项目35项，立项经费超过500万欧元。此外，主持戴姆勒、宝马、捷豹、标致、福特、通用、雷诺、菲亚特、德尔福、卡特彼勒等国际知名企业项目26项，立项经费超过240万欧元。迄今为止发表SCI学术论文144篇，国际会议论文80篇，h-citation index 40，其文章被引频次在西班牙机械工程领域排第一。Payri教授现为国际著名期刊International Journal of Engine Research主编，Atomization and Sprays编委，同时担任了28届欧洲喷雾雾化会议（ILASS-Europe）的主席。此外，Payri教授还是国际发动机燃烧合作组织（Engine Combustion Network）三位负责人之一，负责组织每月一次的线上会议和每年一次的国际研讨会。

主讲内容简介：The concept of passive pre-chamber ignition is becoming an attractive solution to increase the thermal efficiency of future SI engines for passenger cars, due to its ability to accelerate the combustion process. Furthermore, combining this ignition strategy with diluted mixtures (either with air or exhaust gases) has the potential to further enhance engine performance. However, there are still significant obstacles related to understanding the fundamental physicochemical aspects of the concept (turbulence, aerodynamics, energy conversion, jet dynamics, pre-chamber geometry...), which ultimately have limited the integration of this technology into production.

    This presentation aims to extend the level of knowledge of this ignition concept using a state-of-the-art CFD model, validated with an extensive set of experimental measurements and following a methodology specifically developed for this work.
