The following graphs display schlieren plots (cf. Fig. 2.2) for a regularly oscillating three-dimensional configuration withThe initial conditions are analogous to the two-dimensional configurations of the previous section. The detonation channel has the rectangular cross section 10x10.
Godunov-splitting is used for the incorporation of the source term and for the dimensional extension of a hybrid Roe-HLL scheme with MUSCL reconstruction. Automatic time step adjustment for CCFL = 0.95, Van Albada-limiter, 32 Pts/L1/2. Dynamic adaptive mesh refinement with AMROC with two additional refinement levels (refinement factors 2,3) was used. The computational time was 1530 h CPU time on Athlon 1.4GHz.
