Deflagration-to-Detonation Transition in Pipes: The Analytical Theory

Here we discuss the fundamental aspects of the Deflagration-to-Detonation Transition (DDT) phenomenon in the framework of an analytical theory. This approach is capable to predict the pressure rise and the shock wave speed for a given fuel type and concentration, which may be of significant interest to the field-safety engineers designing and assessing petrochemical plants. A locally observed DDT phenomenon observed in the present experiments is also discussed and the measured pressure rise is compared with the theoretical predictions.
