RESUMO

JP-10/air two-phase detonation is numerically studied using the Eulerian code to determine the accuracy of the numerical approach by comparing detonation velocities among three groups: the present study, Tangirala and Dean, and Cheatham and Kailasanath. It was found within those studies that JP-10/air detonation velocities were identical, leading to the conclusion that the present method was valid and numerical simulation could proceed. A two-dimensional numerical study was performed using a commercial code and it was discovered that the detonation velocity of a JP-10 droplet/air mixture (3 micron droplet case) is within 5% lower than that of a JP-10 gas/air mixture and that the Ispf of Pulse Detonation Engine (PDE) initially fueled with a gas/air mixture is slightly higher than that of a PDE initially fueled with a multiphase JP10 liquid/air mixture.
