Numerical Investigation of an Axisymmetric Model Scramjet Assisted with Cavity of Different Aft Wall Angles

Fuel distribution of the (a) nonreacting and (b) reacting flow fields of case-22.5; the streamline is colored by the local distance to the axis of symmetry, and the isosurface is defined as the surface where the partial derivative in the radial direction of streamwise velocity equals -15000 s^-1 to display the boundary of the cavity shear layer.
