Aiaa 2002-3297 Interference between Two Side-by-side Cylinders in Hypersonic Rarefied-gas Flows
Hypersonic rarefied-gas flows near two side-byside cylinders have been studied numerically with the direct simulation Monte-Carlo technique under transitional rarefied-gas-flow conditions (Knudsen numbers from 0.0167 to 10). Strong influences of the geometrical factor (ratio of distance between cylinders to cylinder diameter) and the Knudsen number on the flow structure (the shape of shock wave...

متن کاملComputation of Flow Behind Three Side-by-Side Cylinders of Unequal/Equal Spacing
This paper aims to simulate unstable gap flows of three side-by-side cylinders unequally/equally spaced at T1/d = 1.5 and T2/d = 1.6 in a uniform cross flow (Re=300). The simulation is carried out using ANSYS Flotran 7.0. A mesh-independent study is conducted on a single cylinder at Re=100. The Strouhal number and wake flow characteristics compare well with experimental results. Simulation of t...
متن کاملIB-LBM study on cell sorting by pinched flow fractionation.
Separation of two categories of cells in pinched flow fractionation(PFF) device is simulated by employing IB-LBM. The separation performances at low Reynolds number (about 1) under different pinched segment widths, flow ratios, cell features, and distances between neighboring cells are studied and the results are compared with those predicted by the empirical formula. The simulation indicates t...
متن کاملPhase-Averaged Analysis of Three-Dimensional Vorticity in the Wake of Two Yawed Side-By-Side Circular Cylinders
Thewake flow behind two yawed side-by-sidecircular cylinders is investigated using athree-dimensional vorticity probe. Four yaw angles (α), namely, 0°, 15°, 30° and 45° and twocylinder spacing ratios T of 1.7 and 3.0 were tested. For T = 3.0, there exist two vortex streets and the cylinders behave as independent and isolated ones. The maximum contour value of the coherent streamwise vorticity *...
