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...

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

Tangent double Hopf bifurcation in a differentially rotating cylinder flow.

A tangent double Hopf bifurcation has been found in a rotating cylinder flow driven by the counter-rotation of the top endwall. The codimension-3 tangent double Hopf point has been located using linear stability analysis. The nonlinear analysis of the multiple solutions in a neighborhood of this bifurcation point is performed by numerical solutions of the three-dimensional Navier-Stokes equatio...

Mathematical Modeling of Potential Flow over a Rotating Cylinder (RESEARCH NOTE)

Potential flow over rotating cylinder is usually solved by the singularity method. However,in this paper a mathematical solution is presented for this problem by direct solution of the Laplace’sequation. Flow over the cylinder was considered non-viscous. Neumann and Dirichlet boundaryconditions were used on the solid surfaces and in the infinity, respectively. Because of non-viscous flow,the La...

Non-newtonian Behavior of a Rotating-cylinder Induced Flow

As a cylinder spins in an infinite media, viscous shear forces induce fluid motion and circular streamlines are generated. For Newtonian fluids, a simple analytical solution is possible and widely known. The hydrodynamics of nonNewtonian fluids, however, can be quite complex under such conditions. This paper investigates the behavior of a wide range of non-Newtonian fluids in the infinite cylin...
