Gas-solid flows in nature and industrial applications are characterized by multiscale and
nonlinear interactions that manifest as rich flow physics and pose unique modeling …

▪ Abstract The current understanding of the average flow properties of packed beds and
particle suspensions, in which inertia plays a significant role on the particle length scale, is …

For fluid dynamics simulations, the primary issues are accuracy, computational efficiency,
and the ability to handle complex geometries. Spectral methods offer the highest accuracy …

Gas–solid momentum transfer is a fundamental problem that is characterized by the
dependence of normalized average fluid–particle force F on solid volume fraction ϕ and the …

A Cartesian grid method has been developed for simulating two-dimensional unsteady,
viscous, incompressible flows with complex immersed boundaries. A finite-volume method …

We present an efficient method for solving 2D incompressible viscous flows around multiple
moving objects. Our method employs an underlying regular Cartesian grid to solve the …

We present a novel iterative immersed boundary (IB) method in which the body force
updating is incorporated into the pressure iterations. Because the body force and pressure …

Dispersed particulate flows abound in nature and in engineering applications. In most
cases, the fluid phase is turbulent. The interaction between the fluid phase and the …

Predictions of turbine blade film cooling have traditionally employed Reynolds-averaged
Navier-Stokes solvers and two-equation models for turbulence. Evaluation of several …

The interaction between a fixed particle and decaying homogeneous isotropic turbulence is
studied numerically using an overset grid that provides resolution of all scales of fluid …
