The hypersonic shock/shock interference flow which is well known as the Type IV shock interference heating problem is numerically investigated and the existence of periodical interactions between the bow shock and compression waves generated from the stagnation point of a supersonic jet is assumed. The interaction could have been captured using a higher-resolution finite-difference method proposed by the authors. The principal concept of the present method is to employ the fourth-order accurate compact MUSCL TVD (FCMT) scheme in space difference and a maximum second-order accurate implicit scheme in time integration. The use of the higher-order numerical schemes enables us to capture not only shocks and contact discontinuities but vortices accurately without numerical oscillations. The obtained numerical results are showing extremely complicated flow structures, such as an unsteady supersonic jet, a jet bow shock, unsteady shear layers, and periodical interactions between the bow shock and compression waves. Each of the interactions is generating a contact discontinuity and it is also interacting with following compression waves. Finally the structure of cross stripes by contact discontinuities and compression waves are explained.
