There is much interest in scramjet propulsion for manned and unmanned applications. Early
work focused on hydrogen as the fuel, which has attractive energy per mass properties, but
requires cryogenic storage to keep the fuel volume to acceptable levels. Hydrogen fuel has
short vehicle fuel storage limits and longer refueling times compared to traditional liquid
aviation fuels. For these reasons there is interest in using liquid hydrocarbon fuels more
similar to current aviation fuel. To evaluate current scramjet combustor designs using liquid ?
