2D Fluid Motion Simulation Using the Smooth Particle Hydrodynamic Method

Abstract

2D virtual fluid simulation can help in simulating fluids directly in various problems, such as fluid simulations for education, geological simulations for landslides, and so on. This study aims to simulate the fluid behavior of water in an unhindered medium and observe the fluid particle interactions that occur. This research is simulated using the Python programming language to simulate fluids and using the Wondershare Filmora X application to combine images. This research method uses the Smooth Particle Hydrodynamics method to simulate fluids in a 2-dimensional container with a total of 10,000 particles. The Smooth Particle Hydrodynamics method is used to help model fluids in particle form by deriving the direct force density field from the Navier-Stokes equation. The Navier-Stokes equation is used to find the acceleration and velocity of fluid particles by including external forces, internal forces, and gravity through the Smooth Particle Hydrodynamics method. Acceleration and velocity will be validated due to wall collisions which cause changes in particle position and particle velocity. At the time of visualization, the fluid velocity slows down over time due to damping caused by interactions between fellow particles and particles with walls. And here you can see the fluid behavior of water flowing from a high place to a lower place and the water fluid particles are shaped to follow the container.
