• E123 Effects of Shchelkin Spiral Length on Characteristics of DDT in a Vortex Flow

抄録

The effects of lengths and blockage ratios (BR) of Shchelkin spiral on characteristics of deflagration-to-detonation transition (DDT) in a vortex flow were examined in order to control the DDT distance without losing the simplicity inherent pulse detonation engines (PDEs). A vortex flow field was established in the ignition and transition domains of the detonation tube using a vortex flow type injection. The DDT process was observed by measuring the pressure and ionization current in the detonation tube. The DDT distance decreases with increasing the length of Shchelkin spiral. However, the optimum length of Shchelkin spiral exists. The DDT distance is reduced by about 12.0% when the BR is increased from 38.2% to 45.1%.
