Testo completoFluid particle flows hold significant importance in a variety of industrial applications, particularly in the context of third-generation concentrated solar power plants, where they can be used as both a heat transfer fluid and a storage medium. However, studying these flows presents considerable challenges due to the complex multiscale interactions governing them. Numerical simulation, particularly Direct Numerical Simulation (DNS) methods where the resolution is smaller than the particle diameter, emerges as a promising tool for better understanding these flows and aiding in the design of pilot-scale industrial applications. The increase in computational capabilities and the performance of numerical algorithms has made the particle resolved simulations of fluidized beds increasingly feasible for representative studies.In this thesis, we present a numerical method based on the one-fluid formulation. This method combines the front tracking method with the viscous penalty method to simulate fluid particle flow behaviors. The front tracking method employs a dual mesh system. This system effectively tracks the moving solid interfaces, represented as a moving mesh, across a fixed simulation grid, ensuring accuracy in representing the particle movements. The viscous penalty method, on the other hand, plays a pivotal role in ensuring the fidelity of rigid body motion within the particles. This is achieved by treating the fluid within the particles as an extremely viscous medium, thereby enabling the simulation to realistically mimic the behavior of fluid particles under various conditions.For short-term interactions between particles, a combined collision model is used. This model adeptly accounts for both viscous dissipation and solid dissipation, primarily due to lubrication effects and inelastic contacts between particles, respectively. The nuanced approach of this model allows for more natural simulations of particle interactions, reducing the reliance on arbitrary numerical parameters often seen in other models cited in the literature. The algorithm is implemented in TrioCFD an open-source framework designed for massively parallel computing.The accuracy and reliability of the simulation code were rigorously tested against well-established benchmarks in the literature. Furthermore, the thesis includes a parametric simulation of a lab-scale fluidized bed, comparing the accuracy of the algorithm against both experimental and numerical results. These comparisons demonstrate that the proposed algorithm aligns well with established benchmarks and exhibits good accuracy in its predictions

Testo completoIn this work, we consider the steady transport of a granular medium by a laminar Couette flow for a fixed density ratio of 2.5 and a range of particle Reynolds number, Re p [0.1, 10], and Shields number [0.1, 0.7]. All scales of this two-phase flow are captured (except for the lubrication effects). By solving the Navier-Stokes equations, taking into account the presence of particles using an Immersed Boundary Method (IBM) coupled to a granular solver (Discrete Elements Method - DEM) which solves the Newton equations for each particle, in particular grain-grain interactions (resolution at the microscopic scale). Up-scaling is then performed to describe the flow via equivalent continuous quantities (description at the mesoscopic scale). IBM-DEM simulations allow to quantify all the terms of the so-called mesoscopic model and to characterize the rheology of each phase and that of the equivalent mixture. A second up-scaling is finally performed to reduce the granular flow to a singularity, which corresponds to a boundary condition from the fluid view point. The boundary condition is of Navier’s type. The IBM-DEM simulations suggest that the corresponding "equivalent" slip-lenght scales as
