چکیده

Abstract A Taylor–Galerkin finite element time marching scheme is derived to numerically simulate the flow of a compressible and nonisothermal viscoelastic liquid between eccentrically rotating cylinders. Numerical approximations governing constitutive equations are computed over custom refined unstructured grid piecewise linear Galerkin elements. An original extension DEVSS formulation for fluids introduced stabilise solutions discrete problem. The predictions two models: extended White–Metzner FENE-P-MP presented. Comparisons torque load bearing capacity predicted by both models made range parameters. results highlight significant interacting effects elasticity compressibility on journal resultant load, stability system.

MHD Flow of the Micropolar Fluid between Eccentrically Rotating Disks

This analytical investigation examines the magnetohydrodynamic flow problem of an incompressible micropolar fluid between the two eccentrically placed disks. Employing suitable transformations, the flow governing partial differential equations is reduced to ordinary differential equations. An exact solution representing the different flow characteristic of micropolar fluid has been derived by s...

Angular momentum transport in turbulent flow between independently rotating cylinders.

We present measurements of the angular momentum flux (torque) in Taylor-Couette flow of water between independently rotating cylinders for all regions of the (Ω1, Ω2) parameter space at high Reynolds numbers, where Ω1 (Ω2) is the inner (outer) cylinder angular velocity. We find that the Rossby number Ro = (Ω1 - Ω2)/Ω2 fully determines the state and torque G as compared to G(Ro = ∞) ≡ G∞. The ra...

Pressure Calculation in the Flow Between Two Rotating Eccentric Cylinders at High Renolds Numbers

This paper reports the result of an analytical investigation of a steady, incompressible and viscous flow between two eccentric, rotating cylinders at high Reynolds number. A one dimensional case is far from reality because the gap between the cylinders is very small. Further, when their axes are displaced by a small distance, usually caused by bearing loads, two dimensional effects become obvi...

Hydrodynamic stability of flow between rotating porous cylinders with radial and axial flow

A linear stability analysis was carried out for axial flow between a rotating porous inner cylinder and a concentric, stationary, porous outer cylinder when radial flow is present for several radius ratios. The radial Reynolds number, based on the radial velocity at the inner cylinder and the inner radius, was varied from 215 to 15, and the axial Reynolds number based on the mean axial velocity...

Magnetohydrodynamic instability in differentially rotating compressible flow

Transport of angular momentum is one of the thrust areas of astrophysical flows. Instabilities and hence the turbulence generated by it has been invoked to understand its role in angular momentum transport in hydrodynamic and magnetohydrodynamic regime. Investigation of an unexplored region described by the parameter space Ω e < 0, Ωe being the epicyclic frequency, resulted in a powerful magnet...
