This clear example was chosen because it helped resolve the issue of propagation velocity.
Hence the smoothed VOF which resolves the issue of spurious velocities is shown to be a more viable tool in predicting the flow in microchannels by means of numerical simulations.
In this work, we present an improved VOF model based on smoothing functions that can effectively minimise the issue of spurious velocities, which causes numerical simulations in microchannels to be less accurate.
The solution to momentum, pressure, solid and fluid volume fraction equations everywhere in the domain circumvents the issue of pressure and velocity interpolation, which is a source of spurious oscillations in sharp interface immersed boundary methods.
This issue, including our interpretation of velocity increase in the low-velocity layer, is still open question and should be examined in the future.
In this paper, we investigate the issue of tracking a desired velocity in the least amount of time, for a differential drive nonholonomic wheeled mobile robot with torque inputs.
We have not worked on the problem of obstacle avoidance, nor on the issue of optimization of the velocity curve.
The issues of adopting the velocity components as dependent velocity variables, including the Cartesian and culvilinear ones, for the Navier-Stokes flow computations are investigated.
The controversial issue of alloy scattering and the phenomenon of velocity overshoot are reviewed and discussed.
Highly sensitive, accurate and frequent measurements of velocity and/or position during such whipping in a large number of horses during races could address this issue.
"Too much can be made of velocity.
