N2 - The flowfield characteristics of a relatively small quasi-axisymmetric scramjet vehicle at a Mach 6 flight condition have been investigated numerically. To this end, three-dimensional, compressible, turbulent, reacting flow calculations with a finite rate chemistry model consisting of 33 reactions and 13 species and two-equation SST k-ω RANS model have been performed. Hydrogen is used as the fuel and the injection pressure of fuel is varied from 1 to 7 MPa in order to study the effect of the injection pressure on the flowfields in the scramjet model. The combustion length has been found to decrease as the injection pressure increases. However, rather little thrust gain has been achieved by combustion heat release in the present configurations.
