We describe a pseudo arc-length algorithm for numerical resolution of immiscible compressible multi-material flows with the Mie-Grüneisen type equation of state (EOS) governed by the quasi-conservative five-equation model
The THINC (Tangent of Hyperbola for Interface Capturing) scheme is used as a basis for the reconstruction of grids on the interface cells
Numerical simulation of underwater explosion shows that the pseudo arc-length algorithm can achieve that computational grid capture the detonation wave, five-equation model can be achieved on the material interface capturing by using macroscopic volume fraction, and the THINC scheme can keep the interface sharp and constrain the interface within two or three grids
