Abstract

In this work, a numerical simulation was established by a two-step chemical reaction model and a fifth-order WENO scheme with a third-order TVD Runge-Kutta method to study the cellular detonation wave of H₂-O₂ mixture. The structure of cellular detonation, as well as flow structure around a triple point and combustion in a complicated tube, was studied. The results indicated that front formations of two-dimensional detonation wave were significantly enhanced by the transverse waves. The motion of transverse waves generated triple points, which caused the self-sustained detonation propagation.
