An accurate SPH Volume Adaptive Scheme for modeling strongly-compressible multiphase flows. Part 1: Numerical scheme and validations with basic 1D and 2D benchmarks

•Delta-SPH model is extended for simulating strongly-compressible multiphase flows.•A new Volume Adaptive Scheme is proposed.•Governing equations are discretized with corrected SPH operators.•Strict numerical validations are carried out using challenging benchmarks. In the present work, the single-p...
