Description
Summary:•The fundamental aspects of the Deflagration-to-detonation transition (DDT) phenomenon are presented.•This DDT theory is capable to predict the pressure rise and the shock wave speed for a given fuel type and concentration.•The overpressure of 1.7 MPa for methane and hydrogen was observed from both experiment and theory.•This DDT theory should be of practical interest to engineers designing and assessing petrochemical plants. Herein, we discuss the fundamental aspects of the deflagration-to-detonation transition (DDT) phenomenon in the framework of the analytical theory. This semi-empirical approach facilitates prediction of the pressure rise and the shock wave speed for a given fuel type and concentration, which may be of significant interest for the design and assessment of petrochemical plants by field-safety engineers. The locally observed DDT phenomenon explored in the present experiments is also discussed, and the measured pressure rise is compared with the theoretical predictions.
