A number of approximations have been proposed to estimate basic hydrodynamic quantities, in particular the frequency a limit cycle. One these, RZIF (for Real Zero Imaginary Frequency), calls for linearizing governing equations about mean flow and estimating as imaginary part leading eigenvalue. further reduction, SCM Self-Consistent Model), approximates well, resulting only from nonlinear inter...

A non-direct contact rotary interface uses a viscous fluid as the lubricant working medium. Because oil film friction coefficient formed is extremely small, so it has great application potential in sealing, transmission, thermosolutal convection, and bionics. Research on mechanical seals, wet clutches, dynamic load bearing have proven that micro-textures can effectively improve lubrication perf...

Abstract The internal heat source and reaction effects on the onset of thermosolutal convection in a local thermal non-equilibrium porous medium are examined, where temperature fluid solid skeleton may differ. linear instability nonlinear stability theories Darcy–Brinkman type with fixed boundary condition carried out layer is heated salted from below. <m:math xmlns:m="http://www.w3.org/1998/Ma...

In the present paper, the theoretical investigation of the double-diffusive convection in a micropolar fluid layer heated and soluted from below saturating a porous medium is considered. For a flat fluid layer contained between two free boundaries, an exact solution is obtained. A linear stability analysis theory and normal mode analysis method have been used. For the case of stationary convect...

We describe an interpretation of convection in binary fluid mixtures as a superposition of thermal and solutal problems, with coupling due to advection and proportional to the separation parameter S. Many of the properties of binary fluid convection are then consequences of generic properties of 2 × 2 matrices. The eigenvalues of 2× 2 matrices varying continuously with a parameter r undergo eit...

Sankar et a Mass Transfer (2012), http://dx.doi.org/10.1016 Double-diffusive convection in a vertical annulus filled with a fluid-saturated porous medium is numerically investigated with the aim to understand the effects of a discrete source of heat and solute on the fluid flow and heat and mass transfer rates. The porous annulus is subject to heat and m...
