Measurement of flow behind stationary cylinder placed in rotating gas.

Development of a novel method in TRMC for a Binary Gas Flow Inside a Rotating Cylinder

A new approach to calculate the axially symmetric binary gas flow is proposed Dalton’s law for partial pressures contributed by each species of a binary gas mixture (argon and helium) is incorporated into numerical simulation of rarefied axially symmetric flow inside a rotating cylinder using the time relaxed Monte-Carlo (TRMC) scheme and the direct simulation Monte-Carlo (DSMC) method. The res...

Flow between a stationary and a rotating disk shrouded by a co-rotating cylinder

Boundary layers on stationary and rotating disks have received much attention since von Kármán’s @Z. Angew. Math. Mech. 1, 233 ~1921!# and Bödewadt’s @Z. Angew. Math. Mech. 20, 241 ~1940!# studies of the cases with disks of infinite radius. Theoretical treatments have focused on similarity treatments leading to conflicting ideas about existence and uniqueness, and where self-similar solutions e...

Large-Biot-number non-isothermal flow of a thin film on a stationary or rotating cylinder

Using the lubrication approximation we investigate two-dimensional steady flow of a thin film of fluid with temperature-dependent viscosity on a uniformly heated or cooled horizontal cylinder, which may be stationary or rotating about its axis, in the case when the Biot number (a measure of heat transfer at the free surface) is large. We show that the film thickness (but not the fluid velocity)...

AXIAL FLOW OF CASSON PLASTIC MODEL IN ANNULUS WITH A ROTATING INNER CYLINDER

Flow Kinematics in Variable-Height Rotating Cylinder Arrays

Experimental data are presented for large arrays of rotating, variable-height cylinders in order to study the dependence of the three-dimensional mean flows on the height heterogeneity of the array. Elements in the examined arrays were spatially arranged in the same staggered paired configuration, and the heights of each element pair varied up to 637.5% from the mean height (kept constant acros...
