Présentation

Executive Statement

Professor at INSA Centre Val de Loire, Bourges, attached to the laboratory PRISME (Multi-field research laboratory in engineering science).

Expert in mechanisms of explosions and their effects – Investigations by experiments at small scale and by simulation with CFD codes.

Key words

Blast effects - Detonation - Deflagration - Explosions - External dynamics of explosions - Industrial safety - Physical modelling of explosions - Propagation of shock waves.

Field of expertise

I am specialized in analysis of explosions phenomena (deflagration and detonation) and shock wave propagation in unconfined and confined without and with obstructions environments. The adopted methodology is essentially experimental and at small scales. This approach allows for developing phenomenological and analytical laws of propagation and multiple reflection shock waves. The Explosion group owns pressure gauges, high-speed camera to analyse reflection of shock waves. Some numerical simulations have been conducted too with industrial partners. The investigations meet planned needs of defence and civil industries.

Concerning the mechanisms of deflagration I investigated the mechanism of formation and acceleration in non-uniform gaseous mixtures without and with obstacles (leakage, concentration and pressure measurements and visualisation).
