Abstract

In the present study, experiments on liquid-fuel air-breathing pulse detonation engines (PDEs) are conducted using a low-vapor-pressure fuel: Jet A-1. Past studies have mostly focused on demonstrating the use of high-vapor-pressure fuels (e.g., heptane) or low-vapor-pressure fuels (e.g., JP8 and Jet A-1) with a predetermined air temperature (e.g., 398 K) or with some pretreatments on the liquid fuels (e.g., preheating of fuel). Based on previous notable studies [1–3], critical conditions for success or failure of liquid-fuel PDEs are mainly related to fuel types, inlet air temperatures, and spray droplet sizes. Essentially, these conditions determine the amount of pre-vaporized fuel prior to ignition. The present paper attempts to establish a criterion for detonation transition of two-phase Jet A-1/air mixtures.
