Numerical simulations of ice droplet trajectories and collection efficiency on aero- engine rotating machinery

This paper presents a methodology for threedimensional numerical simulations of supercooled water droplet trajectories through aeroengine rotating machinery. Both flow and droplets’ governing equations are formulated and solved in the reference frame of rotating blades. A Eulerian-Lagrangian approach is used for the continuous and discrete phases with one-way interaction model to simulate the a...

Dense Media Scattering Based on Numerical Simulations

The frequency and polarization dependence of scattering by the densely packed spherical particles is rigorously studied with the Monte Carlo simulations for solving both 2and 3-dimensional Maxwell's equations at microwave frequencies. Numerical simulation solutions indicate that the frequency dependence of densely packed sticky small particles is much weaker than that of independent scattering ...

Numerical Simulations on PC Graphics Hardware

On recent PC graphics cards, fully programmable parallel geometry and pixel units are available providing powerful instruction sets to perform arithmetic and logical operations. In addition to computational functionality, pixel (fragment) units also provide an efficient memory interface to local graphics data. To take full advantage of this technology, considerable effort has been spent on the ...

NUMERICAL SIMULATIONS OF THE PHASE TRANSITIONS IN CLUSTERS

We have studied the phase transitions in atomic clusters by molecular dynamics simulation, assuming Lennard-Jones interatomic pair potential. Calculations are performed by DAP parallel computer. The results are analyzed by simulating their orientational distribution plots (dot-plot), and neutron diffraction patterns. It is shown that all the main features of the bulk phase transitions are e...
