چکیده
Discrete element based simulations of granular ow in a d velocity space are compared with a particle code that solves kinetic granular ow equations in two and three dimensions The binary collisions of the latter are governed by the same forces as for the discrete elements Both methods are applied to a granular shear ow of equally sized discs and spheres The two dimensional implementation of the kinetic approach shows excellent agreement with the results of the discrete element simulations When changing to a three dimensional velocity space the qualitative features of the ow are maintained However some ow properties change quantitatively MSC C F B B

Effects of coupling on turbulent gas-particle boundary layer flows at borderline volume fractions using kinetic theory
This study is concerned with the prediction of particles’ velocity in a dilute turbulent gas-solidboundary layer flow using a fully Eulerian two-fluid model. The closures required for equationsdescribing the particulate phase are derived from the kinetic theory of granular flows. Gas phaseturbulence is modeled by one-equation model and solid phase turbulence by MLH theory. Resultsof one-way and...

متن کاملSimulation of nanodroplet impact on a solid surface
A novel computational fluid dynamics and molecular kinetic theory (CFD-MK) method was developed to simulate the impingement of a nanodroplet onto a solid surface. A numerical solution of the Navier–Stokes equation using a volume-of-fluid (VOF) technique was used to model nanodroplet deformation. Dynamic contact angle during droplet impact was obtained by molecular kinetic theory. This dynamic c...
متن کاملStepped Spillway Performance: Study of the Pressure and Turbulent Kinetic Energy versus Discharge and Slope
In the present study, flow over flat and pooled stepped spillways was simulated three dimensionally. The VOF method and k- ε (RNG) turbulent model was used to simulate the flow over the stepped spillway. The results indicated that the numerical model was acceptably capable of simulating the flow over the pooled and flat stepped spillways for different discharges. Following that, the effect of d...

متن کاملKinetic modeling of methylene blue adsorption onto acid-activated spent tea: A comparison between linear and non-linear regression analysis
The kinetic study of methylene blue (MB) adsorption using acid-activated spent tea (AAST) as an adsorbent from aqueous solution with the aim of comparing linear and non-linear regression analysis methods was performed at varying initial MB concentrations (10-100 mg/l). Hence, spent tea leaves, which were activated using concentrated sulfuric acid, were prepared. The physicochemical characterist...
