A state- and rate-dependent constitutive model for granular materials with interstitial fluid: solid-like, fluid-like behaviours and their transitions

Yadong Wang, Xiaogang Guo, Wei Wu, Hong Zhou et autres

Granular materials exhibit solid-like and fluid-like behaviour in different flow regimes, governed by intergranular frictions, collisions and viscous force from the interstitial fluid. In this paper, a state- and rate-dependent constitutive model is proposed to describe the solid-like and fluid-like behaviours in …

Numerical Study of Hydrodynamics Characteristics of Cylinders with Intermittent Spanwise Arrangements

S. D. Yu, Erxian Zeng, Yadong Wang, Siyuan He et autres

Subsea pipelines with intermittent spanwise arrangements are commonly encountered in offshore engineering, yet their complex hydrodynamic interactions remain insufficiently understood. In this study, three-dimensional numerical simulations were conducted to investigate the hydrodynamics of intermittently spanning cylinders at a Reynolds number of 40,250. …

Numerical Model for Granular Flow With Interstitial Fluid

Yadong Wang

ABSTRACT We present a constitutive model for the mechanical behavior of granular flow for both solid‐like and fluid‐like regimes. The stress rate tensor is decomposed into rate‐independent and rate‐dependent parts. The hypoplastic model is used for the rate‐independent part, while the ‐type …

Research on temperature prediction of shearer cable based on bidirectional long short-term memory

Lijuan Zhao, Guocong Lin, Yadong Wang, Bo Xie et autres

This study investigates the temperature behavior of the MCP-0.66/1.14 (3∗95 + 1∗35 + 4∗10)shearer cable, focusing on the effects of ambient temperature and load current. A 3D simulation model was created using the Rhino-Grasshopper toolset, and a bidirectional coupled electromagnetic-thermal simulation model …

A SPH Model Bridging Solid‐ and Fluid‐Like Behaviour in Granular Materials

Yadong Wang

ABSTRACT We propose a smoothed particle hydrodynamics (SPH) model bridging the gap between solid‐ and fluid‐like behaviour observed in granular materials. The key innovation of the proposed approach lies in the decomposition of the stress gradient into rate‐independent and rate‐dependent parts, which …
