  3. Abstract:
  4. In this work, Compressible Smooth Particles Hydrodynamics (C-SPH) is applied for numerical simulation of impulsive wave. Properties of linear and angular momentum in SPH formulation are studied. Kernel gradient of viscous term in momentum equation is corrected to ensure preservation of angular momentum. Corrected SPH method is used to simulate solitary Scott Russell wave and applied to simulate impulsive wave generated by two-dimensional under water landslide. In each of test cases, results of corrected SPH are compared with experimental results. The results of the numerical simulations and experimental works are matched and a satisfactory agreement is observed. Furthermore, vorticity counters computed by the corrected SPH are compared with uncorrected SPH so that the effect of preservation of angular momentum is illustrated. Comparison between experimental and computational results proves applicability of The C-SPH method for simulation of these kinds of problems. © 2009 Taylor & Francis Group
