Translational friction coefficient of a permeable cylinder in a sheet of viscous fluid ?
نویسنده
چکیده
We calculate the translational friction coefficient and the translational diffusion coefficient of a permeable cylinder moving in a sheet of fluid which is embedded on both sides in a fluid of much lower viscosity. The result, which is an asymptotic expression valid in the limit of small ratios of the viscosities, is derived by the method of matched asymptotic expansions.

Possessions of viscous dissipation on radiative MHD heat and mass transfer flow of a micropolar fluid over a porous stretching sheet with chemical reaction
This article presents the heat and mass transfer characteristics of unsteady MHD flow of a viscous, incompressible and electrically conducting micropolar fluid in the presence of viscous dissipation and radiation over a porous stretching sheet with chemical reaction. The governing partial differential equations (PDEs) are reduced to ordinary differential equations (ODEs) by applying suitable si...
متن کاملFriction Coefficient of a Disk in a Sheet of Viscous Fluid: Numerical Calculation
The translational friction coefficient of a porous cylindrical disk moving in a sheet of fluid which is embedded on both sides in a fluid of different viscosity, is calculated numerically for a wide range of the relevant parameters. These results are used to evaluate the region of validity of certain asymptotic formulae which have been derived previously in the limit of small ratios of the visc...

The paper aims at investigating the effects of chemical reaction and thermal radiation on the steady two-dimensional laminar flow of viscous incompressible electrically conducting micropolar fluid past a stretching surface embedded in a non-Darcian porous medium. The radiative heat flux is assumed to follow Rosseland approximation. The governing equations of momentum, angular momentum, energy, ...

A numerical study has been conducted to investigate the modelling of steady two-dimensional stagnation-point flow and diffusion of chemically reactive species of a viscous and incompressible fluid past a permeable quadratically stretching/ shrinking sheet. Similarity transformation has been used to reduce the governing nonlinear partial differential equations into a system of nonlinear ordinary...

In the present analysis, the Dufour and Soret effects on unsteady heat-mass transfer of a viscous incompressible Powell-Eyring fluids flow past an expanding/shrinking permeable sheet are reported. The fluid boundary layer develops over the variable sheet with suction/injection to the non-uniform free stream velocity. Under the symmetry group of transformations, the governing equations along wit...
