Abstract
For increasing the ability of ignition and flame holding of large scale scramjet, the strut-rocket scramjet is developed, which consists of main strut in isolator, strut rocket and circular combustor. The numerical simulation including multi-steps chemical mechanisms was developed to investigate the reactive flow characteristics for liquid hydrocarbon supersonic combustion in circular combustor strut-rocket scramjet which is combined with pylons and cavity. It is indicated that the combination of strut-rocket and pylons is the paramount mechanism for flame holding. The results show that the strut-rocket scramjet can provide robust ignition and combustion efficiency and wide operability for ambient liquid hydrocarbon fuel in large scale combustor.
