The ignition delay of various nano-fuels was compared with the base fuel (i.e. aircraft turbine engine fuel) to study the feasibility of use in high-speed aerospace applications (i.e. pulse detonation engines). The base fuel was mixed with two different nano-particles, titanium dioxide (TiO2) and multi-walled carbon nanotube (MWCNT), to develop a nano-fuel that can be employed for regenerative cooling of combustor walls before injection. A shock tube was employed to carry out the experiments where the liquid fuel was introduced in the test section as a wall droplet. From the experiments, an increase in the ignition delay was observed for the titanium dioxide nano-fuel whereas a slight reduction in the ignition delay was observed for the MWCNT nano-fuel.
