Analytical solution of an Eulerian dilute particle-laden flow problem

development of an explicit eulerian method for treating particle laden turbulent flow in dust collectors

GPU acceleration of Eulerian–Lagrangian particle-laden turbulent flow simulations

Acceleration of an existing MPI-based, particle-laden turbulent flow simulation code is achieved using up to four NVIDIA GPU devices. The overall design is to transfer the entire flow velocity, temperature, and humidity fields to each device, and compute particle trajectories entirely on the GPU hardware. For one-way coupled turbulent flow simulations, accurate simulations can be achieved for l...

Hybrid High-order Eulerian-Lagrangian methods for simulations of particle-laden flow with shocks

The development of a Hybrid high order Eulerian-Lagrangian algorithm to simulate shock wave interactions with particles is discussed. The Hybrid high order WENO/central finite difference scheme is assessed in three-dimensional simulations, as well as the effective use of the high order polynomials and regularization techniques in the approximation to the singular source term in the advection eq...

An analytical solution for Kepler’s problem

In this paper we present a framework which provides an analytical (i.e., infinitely differentiable) transformation between spatial coordinates and orbital elements for the solution of the gravitational two-body problem. The formalism omits all singular variables which otherwise would yield discontinuities. This method is based on two simple real functions for which the derivative rules are only...

Predictions of gas r particle flow with an Eulerian model including a realistic particle size distribution

This paper presents a computational study of the flow behavior in a cold-flow pilot-scale circulating fluidized bed. A multi-fluid Ž . Computational Fluid Dynamics CFD model has been developed and verified against experimental data reported in the literature. The flow model is based on an Eulerian description of the phases where the kinetic theory of granular flow forms the basis for the turbul...
