Shear-driven flow in an elliptical enclosure generated by an inner rotating circular cylinder

Numerical investigation of natural convection phenomena in uniformly heated trapezoidal Cylinder inside an elliptical Enclosure

A numerical study of the natural convection of the laminar heat transfers in the stationary state was developed in a horizontal ring and compared between a heated trapezoidal internal cylinder and a cold elliptical outer cylinder. This annular space is traversed by a Newtonian and incompressible fluid. The Prandtl number is set to 0.7 (air case) for different Rayleigh numbers. The system of equ...

Computation of Sound Generated by Flow over a Circular Cylinder: an Acoustic Analogy Approach*

The sound generated by viscous ow past a circular cylinder is predicted via the Lighthill acoustic analogy approach. The two dimensional ow eld is predicted using two unsteady Reynolds-averaged Navier-Stokes solvers. Flow eld computations are made for laminar ow at three Reynolds numbers (Re = 1000, Re = 10; 000, and Re = 90; 000) and two di erent turbulent models at Re = 90; 000. The unsteady ...

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

Rapidly rotating cylinder flow with an oscillating sidewall.

We present numerical simulations of a flow in a rapidly rotating cylinder subjected to a time-periodic forcing via axial oscillations of the sidewall. When the axial oscillation frequency is less than twice the rotation frequency, inertial waves in the form of shear layers are present. For very fast rotations, these waves approach the form of the characteristics predicted from the linearized in...
