[2C12-20-01] Coupled DEM-LBM Simulation of Underwater Drop of Variously Shaped Objects
Keywords:Coupled solid-fluid model, Discrete element method, Validation
This paper presents the simulation of an underwater drop experiment using a coupled DEM-LBM model in two-dimensional conditions, focusing on object shapes. The shapes of the objects are circular, rectangular, and L-shaped, and the dropping behavior of these objects is measured by image analysis in the model experiment. By comparing the results, the validity of the coupled solid-fluid model based on the DEM-LBM is investigated. The characteristics of the underwater drop experiment as a method of validation are also discussed.
