Numerical investigation of unsteady detonation waves in combustion chamber using Shchelkin spirals
: Pulse Detonation Engine (PDE) is considered to be a propulsive system of future air vehicles.The main objective is to minimizing the Deflagration to Detonation transition run-up distance and time by placing Shchelkin spiral with varying pitch length.Here we have considered blockage-area ratio is 0.5 as optimal value from review of previous studie
