چكيده فارسي :
In this study, the unsteady 2D dam break problem is solved by
weakly compressible SPH with water as a Newtonian fluid
and a thixotropic gel as a non-Newtonian fluid. In this method,
the flow domain is replaced by several representative particles
and the mass and momentum conservation equations are
solved in a Lagrangian frame work for each representative
particle. First, the Newtonian case is verified with previous
numerical and experimental published results. Then the
thixotropic gel is modeled by Moore rheological model and
several simulations are performed to investigate the effects of
the model constants. Furthermore, the differences of
Newtonian and thixotropic fluid flow including free surface
shape and leading edge position are mentioned.
