Macroscopic modelling for screens inside a tuned liquid damper using incompressible smoothed particle hydrodynamics

Liquid sloshing inside a Tuned Liquid Damper (TLD) equipped with screens introduces significant numerical modelling challenges. A 2D Incompressible Smoothed Particle Hydrodynamics (ISPH) model employing a novel macroscopic screen model is presented to capture the complex flow associated with screens and significantly minimize the high computation cost of traditional microscopic screen models. The macroscopic screen model is based on Ergun's …
