The shape of particles is a critical determinant that significantly influences the accuracy discrete element simulations. To reduce discrepancies between model wheat seeds and actual particle shapes, to enhance Computational Fluid Dynamics-Discrete Element Method (CFD-DEM) coupling simulations in gas–solid two-phase flow studies, We employed laser scanning inverse modeling techniques develop three-dimensional (3D) reconstruction seed. Subsequently, we Rocky DEM simulation software polyhedron...
Ultrasonic detection is one of the main methods for information and has advantages in soil detection. signals attenuate soil, resulting unique propagation laws. This paper studies laws ultrasound focusing on characteristics ultrasonic continuous at transducer–soil interface. study uses excitation frequency amplitude as experimental factors employs discrete element simulation method to analyze vibration particles. It reveals relationship between changes pressure interface movement transducer....
Acoustic attenuation is a significant index in acoustic detection, which can reflect large number of physical properties the medium, so it vital. This work aims to study relationship between soil particle movement and wave then explore mechanism. paper used wave-soil model established by discrete element method (DEM) conduct simulation experiments propagation under different emission parameters compression ratios. The time-varying curves spatial trajectory were obtained. eigenvalues...
