The effects variable viscosity on a steady free convective boundary layer flow of a dusty fluid past a vertical permeable stretching surface is studied. The system of non linear partial differential equations governing the equations motion are reduced to a system of ordinary differential equations using similarity transformations. The resultant boundary value problems are then solved numericall...

This work is concerned with the series solutions for the flow of third-grade non-Newtonian fluid with variable viscosity. Due to the nonlinear, coupled, and highly complicated nature of partial differential equations, finding an analytical solution is not an easy task. The homotopy analysis method HAM is employed for the presentation of series solutions. The HAM is accepted as an elegant tool f...

Abstract. In the present study, an analysis is carried out to investigate the effects of variable chemical reaction, thermophoresis, temperature-dependent viscosity and thermal radiation on an unsteady MHD free convective heat and mass transfer flow of a viscous, incompressible, electrically conducting fluid past an impulsively started infinite inclined porous plate. The governing nonlinear par...

An analysis is carried out to investigate the effects of variable chemical reaction, thermophoresis, temperaturedependent viscosity and thermal radiation on an unsteady MHD free convective heat and mass transfer flow of a viscous, incompressible, electrically conducting fluid past an impulsively started infinite inclined porous plate by taking into account the viscous dissipation effects. The g...

This paper describes the experimental study of viscosity measurement error in the vibrational type viscometer, which measures viscous damping of the oscillating circular plate in a fluid in continuously increasing temperatures. The experiments are carried out to measure non-uniformity of the temperature field in the test cup of the vibrational viscometer in continuously increasing temperatures,...

This study explores the influence of an inclined magnetic field and variable viscosity on entropy generation in steady flow a couple stress fluid channel. The walls channel are stationary non-isothermal. is driven due to pressure gradient gravitational force. Reynold’s model for temperature-dependent was used. dimensionless, non-linear coupled equations momentum energy solved, we obtained analy...
