Absolute Permeability Calculation by Direct Numerical Simulation in Porous Media

Simulating fluid flow at micro level is an ongoing problem. Simplified macroscopic flow models like Darcy’s law is unable to estimate fluid dynamic properties of porous media. The digital sample reconstruction by high resolution X-ray computed tomography scanning and fluid-dynamics simulation, together with the increasing power of super-computers, allow to carry out pore-scale simulations throu...

Direct Numerical Simulation of Jet Actuators for Boundary Layer Control

The paper presents a method to perform direct numerical simulations (DNS) of a jet actuator flow inside a turbulent flat plate boundary layer (TBL). A structured finite difference method is used for the simulations. The numerical scheme is adapted to account for the large scale differences both in geometric and fluid dynamic aspect. Analytical mesh transformations have been implemented to resol...

Direct Numerical Simulation of Jet in Crossflow actuators

Jet vortex generators have been proven to provide a mechanism to positively control boundary layer flows. The present paper illustrates a method to perform direct numerical simulations (DNS) of a jet actuator flow inside a laminar boundary layer. A structured finite difference method is used for the simulations. The numerical scheme was adapted to account for the large scale differences both in...

Numerical simulation of toner jet method for nonimpact printing

The toner jet method has been previously proposed to perform electrophotographic nonimpact printing easily. To clarify the fundamental properties of this method, the jet behavior of toner is studied through simulation on a personal computer. The mesh electrode is assumed to be inserted halfway between the development roller and the paper-back electrode. This is done to control the locus and the...
