Lattice Gas Automata of Fluid Dynamics for Unsteady Flow
Abst ract. We st udy lat tice gas automata. of fluid dynamics in the incompressible flow limit . It is shown t hat t he viscosity effect on the transition layer from the steady uniform velocity in one strea.m to the steady uniform velocity in another , adja cent strea m produces t he correct profile. We further study t he intr insic damping or smoothing action of viscous diffusion and show that...
متن کاملParallel Program Complex for Unsteady Viscous Gas Flow Simulation
This paper concerns with the future development of a parallel program package for 3D viscous gas flow simulation presented in [1]. One of the restrictions of this package was its orientation on use of only structured non-uniform meshes. This restriction may be rather taxing when high accuracy resolution of the solution particularities in small regions is needed. Using of regular non-uniform mes...
متن کاملGas-flow animation by unsteady heating in a microchannel
We study the flow-field generated in a one-dimensional wall-bounded gas layer due to an arbitrary small-amplitude time variation in the temperature of its boundaries. Using the Fourier transform technique, analytical results are obtained for the slip-flow/Navier–Stokes limit. These results are complemented by low-variance simulations of the Boltzmann equation, which are useful for establishing ...
متن کاملUnsteady Flow Volumes
Flow volumes [1] are extended for use in unsteady (timedependent) flows. The resulting unsteady flow volumes are the 3 dimensional analog of streaklines. There are few examples where methods other than particle tracing have been used to visualize time varying flows. Since particle paths can become convoluted in time there are additional considerations to be made when extending any visualization...
متن کاملSediment Transport in Unsteady Flow Conditions
Sediment transport under unsteady flow condition is studied experimentally. In the first step, sediment transport under different steady flow conditions was measured and an empirical equation was derived for its calculation. In the next step, two continuous and three stepwise hydrographs were generated in the flume, and their sediment transport rate was measured. The continuous hydrographs were...
