Locally refined discrete velocity grids for stationary rarefied flow simulations
Most of deterministic solvers for rarefied gas dynamics use discrete velocity (or discrete ordinate) approximations of the distribution function on a Cartesian grid. This grid must be sufficiently large and fine to describe the distribution functions at every space position in the computational domain. For 3-dimensional hypersonic flows, like in re-entry problems, this induces much too dense ve...

15 صفحه اولA Study of Flow and Mixing in Bubbly Gas-Liquid Pipe Flow Generated by a Grid
The spreading of a tracer in a bubbly two-phase grid-generated turbulent flow system is studied. In this work both particle image velocimetry (PIV) and planer laser-induced <span style="font-size: 10pt...
متن کاملMultigrid for Locally Refined Meshes
A two-level method for the solution of nite element schemes on locally reened meshes is introduced. The upper bound on the condition number implies, in some cases, mesh-independent convergence, as is veriied numerically for a diiusion problem with discontinuous coeecients. The discontinuity curves are not necessarily aligned with the coarse mesh; indeed, numerical applications with ten levels o...
متن کاملexperimental and numerical modelling of flow pattern on
abstract weirs are the most common structures for discharge measurement in engineering research. streamline curvature, non hydrostatic pressure distribution on weir and nappe adherence to the weir lead to differences between calculated and measured discharges. thus discharge coefficient, which is the ratio of real and theoretic discharges, is usually less than unity. in circular weirs the press...
