WebApr 13, 2024 · The TTS model (Zhang and Cheng 2024) was developed to describe the thermo-hydro-mechanical coupling behavior of saturated soils based on a theory of nonequilibrium thermodynamics referred to as Granular Solid Hydrodynamics [(GSH) (Jiang and Liu 2003, 2007, 2009)].The TTS model uses a hyperelastic relation to … Webhydrodynamic framework starting from transient elasticity, and call it GSH, for granular solid hydrodynamics. The paper is organized as follows. In Sect. 2, we discuss to what …

WebJun 30, 2024 · Conclusions. In this paper, a multi-phase Eulerian–Eulerian two-fluid method (TFM) coupled with the kinetic theory of granular flow (KTGF) was used to study the impact of baffles and fluxtube on the hydrodynamic of the gas–solid fluidized bed. Adding a baffle can change the gas bubble radial distribution. WebStarting from the physics of granular deformation and its depletion by jiggling, we have identified the variables and derived the structure of the equations governing their temporal evolution [24], calling it gsh, for granular solid hydrodynamics. But our second step is not yet complete, and some proposed functional dependencies are still ... origincount

WebThe development of particle receivers handling granular solids as HTFs and TES media is of great interest, since they could withstand temperatures of over 1000 °C [5]. Moreover, many solid materials are involved in high temperature chemical processes, allowing Thermochemical Energy Storage (TCES). ... Hydrodynamic control is fundamental for ... WebJun 6, 2024 · For this purpose, the macroscopic fluidity of the material is modeled through concepts inspired by dynamic fracture mechanics and granular solid hydrodynamics. Specifically, the relationship between dynamic grain-scale processes and bulk dissipation relies on the evolution of a state variable linked to microscale entropy fluctuations, here ... WebDec 6, 2024 · By analogy with Hertz contact, the contact ball is compared to a granular solid, and the spring is compared to a Hooke solid. The elastic potential energy density function of granular materials is given as follows: 33 33. Y. Jiang and M.
