Smoothed Particle Hydrodynamics (SPH) is a meshless method used widely to solve problems such as fluid flows. Due to its meshless property, it is ideal to solve problems on complex geometry. In this paper, boundary treatment were implied for the rectangular pipe flow simulations using SPH. The repulsive force is applied to the boundary particles along with the improved virtual particles on different geometry alignment. The water flow is solved using incompressible SPH and will be examined throughout the simulation. Results from this simulation will be compared with single layered virtual particles. Based on the result of the study, it is found that the improved virtual particles is more accurate and stable.
