ICDERS 2025

30th International Colloquium on the Dynamics of Explosions and Reactive Systems

July 27 – August 1, 2025

University of Ottawa, Ottawa Canada

Scientific program

The International Colloquium on the Dynamics of Explosions and Reactive Systems (ICDERS) has been held every two years since its founding in 1967 by N. Manson, A.K. Oppenheim, and R. Soloukhin. The colloquium has been the premier international forum for the presentation of scientific contributions in the fields of explosions and unsteady combustion, where there is strong coupling between reaction and fluid mechanics. It is recognized by The Combustion Institute as a Specialists Meeting on the fluid dynamics of combustion.

Information to speakers

Oral presentations should be 20 minutes long. The question period will be 2 minutes, followed by 3 minutes to change speakers. Presenters are encouraged to upload their presentations onto the podium computer using a USB 2 key prior to the first session of the day. Alternatively, speakers can use their own laptop and connect to the podium via an HDMI cable, which will be provided. Please bring any adaptor you may need.

Posters are to be installed in the atrium of the conference venue on the provided poster boards. The boards are 120 cm by 120 cm (approximately 4 feet by 4 feet).
