The hydrodynamics of a two-dimensional bed reactor were studied computationally. To describe the particulate phase stress in the Eulerian-Eulerian two-fluid model, the kinetic theory of granular flow has been used. Syamal O'Brien drag function was used to calculate momentum exchange coefficients between gas and solid phases. We specified diameter of glass beads which is 300μm and restitution coefficient...
In this paper, we present a new adaptive model for real-time fluid simulation with complex boundaries based on smoothed particle hydrodynamics (SPH) framework. Firstly, we introduce an adaptive SPH framework that is based on our character field function composed of 4 factors: geometrical complexity, boundary condition, physical complexity and complementary condition in terms of the neighboring particle...
Two-phase flow problems are presented using the method of smoothed particle hydrodynamics (SPH). The combination of meshless and lagrangian nature inherent in the SPH method offers the advantages in treating large deformations, large inhomogeneities and tracing interfaces in the two-phase flow process. Two cases are solved using a SPH code developed at ACES. It is found that major physics of the two-phase...
