The project is the purchase of a film recording system at very high speed and resolution for the study of the cellular structure of detonations in homogeneous gases or with droplet suspension. The scientific expectations are the identification of very fast and very small-scale phenomena whose lack of knowledge hinders the understanding and modeling of detonations, and its use in explosion mitigation devices and detonation engines. This latest research theme, in which the P' Institute plays a pioneering role, is very active in laboratories in major industrial countries. With this project, P' aims to maintain and develop this international recognition.
