    Abstract
  • The detonation characteristics of fuel (PO, IPN, C5~C6, hexane, heptane, Decane)-air cloud were studied in shock tube. The critical initiation energy was measured by the up and down method and cell size by smoked metallic foil. The comparison of detonation characteristics among these fuels was also carried. Results demonstrate that the relationship of critical initiation energy and equivalence ratio shows an U shape curve, the minimal critical energy is obtained when equivalence ratio is slightly larger than 1. The conclusion is similar to the gaseous detonation. These experimental results help us deeply understanding the detonation nature of hydrocarbon-air mixtures.
