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...
متن کاملThe Hydrodynamic Stability of Inviscid Flow between Coaxial Cylinders.
where R1 and R2 are, respectively, the radii of the inner and the outer cylinders. The presence of viscosity inhibits the onset of instability and condition (3) must be violated by a certain determinate extent before instability can arise. The extent of this inhibition has been considered by a number of authors since G. I. Taylor first investigated the problem.1 The equations of viscous flow al...
متن کاملHydrodyna ic stability of viscous flow between rotating cylinders with radial flow
A linear stability analysis has been carried out for flow between porous concentric cylinders when radial flow is present. Several radius ratios with corotating and counter-rotating cylinders were considered. The radial Reynolds number, based on the radial velocity at the inner cylinder and the inner radius, was varied from -30 to 30. The stability equations form an eigenvalue problem that was ...
متن کاملInviscid Compressible Flow in Meridional Plane of an Axial Flow Compressor
In this paper it is attempted to investigate the behavior of an inviscid flow in the meridional plane of an axial flow compressor. For this purpose the 3-D unsteady Euler equations in cylindrical coordinate are averaged in tangential direction. Therefore, the equations are reduced to a 2-D system. By averaging the tangential component of momentum equation, a blade force will result. Axial and r...
متن کاملAn experimental study on hydraulic behavior of free-surface radial flow in coarse-grained porous media
The equations of fluids in porous media are very useful in designing the rockfill and diversion dams, gabions, breakwaters and ground water reserves. Researches have been showed that the Forchheimer equation is not sufficient for the analysis of hydraulic behavior of free-surface radial flows; because, in these flows, in addition to the hydraulic gradient and velocity, the variable of radius is...
