Validation of DualSPHysics for viscous Newtonian flow fronts

Résumé

Viscous, surging flow fronts are encountered in many applications in geophysics such as debris-, mud-and lavaflows. Few applications of the SPH method for low Reynolds, viscous flows have been rigorously validated against experimental data. In this paper, the validation of the DualSPHysics software against well documented experimental data of a laminar viscous flow front is studied. Modelling viscous Newtonian flow fronts requires the use of accurate boundary conditions, including noslip at the wall. A convergence study analyzes the performance of the software using both bulk behaviour and front shape and detailed velocity fields along the flow. Overall, the use of the DualSPHysics solver is validated for such flows. Macroscopic dynamics and internal dynamics are well reproduced.
