Abstract

In this paper, we perform numerical simulations of supersonic flow over a 15◦ -45◦ doublewedge geometry using a time-implicit spectral discontinuous finite element method (DG-SEM). The particular geometry configuration studied in this paper generates a set of shock-shock interactions classified by Edney as Type V [1]. A defining characteristic of this shocked flowfield is the high degree of anisotropy that is generated due to the influence of the wedge angles on the development of the shock-shock interactions. Numerically, this is particularly challenging as it imposes a burden on the numerical scheme to effectively capture the spectrum of length scales generated by this shocked flow.
