Motivated by magnetic polymer manufacturing applications, the present research article examines theoretically hydromagnetic boundary layer flow of an electrically conducting non-Newtonian couple stress fluid due to a transient shrinking (contracting) porous sheet. The conservation partial differential equations for mass and momentum are rendered into fifth-order nonlinear ordinary equation via ...

An analysis of peristaltic flow of a couple-stress fluid, with immersed nanoparticles, in an asymmetric channel having flexible walls is presented in this paper. General boundary conditions on velocity, temperature and concentration of nanoparticles are used for the analysis. Thermophoresis and Brownian diffusion effects govern the motion of nanoparticles. Long wave length approximation and low...

the aim of present paper is to provide mathematical modelling for the two-dimensional mhd flow with induced magnetic field. the flaws in the already existing equations have been pointed out. the results of low magnetic reynolds number approximation are recovered as a special case from the developed equations. as an example, the peristaltic flow for a couple stress fluid in a channel is consider...

This article investigates the magnetohydrodynamic (MHD) three-dimensional flow of couple stress nanofluid subject to the convective boundary condition. Flow is generated due to a nonlinear stretching of the surface in two lateral directions. Temperature and nanoparticles concentration distributions are studied through the Brownian motion and thermophoresis effects. Couple stress fluid is consid...

In this paper, the vibration of microbeams due to a temperature pulse has been investigated. The thermoelastic coupled equations for microbeam resonator have been derived via the modified theory of couple stress in connection with the generalized thermoelasticity with relaxation time. The analytical expressions for studied fields due to modified couple stress for the microbeam have been obtaine...

In this paper the two-dimensional flow of a micropolar fluid through porous medium over a continuously moving porous vertical plate under the combined buoyancy effects of thermal and heat source has been studied under the action of transverse magnetic field taking into account the thermal radiation field. The Roseland approximation is used to describe radiative heat transfer in the limit of opt...

In this paper, we study the flow of two immiscible fluids namely, couple stress fluid and Jeffrey in a porous channel. Instead classical no-slip conditions on boundaries, used slip boundary conditions, which are more realistic meaningful. addition, inclined magnetic field effects flow. The flowing adjacent to each other region I II, respectively, horizontal nondimensionalized governing equation...

Couple stresses because of magnetic particles additives on the lubrication performance a journal bearing system was embraced and scrutinized in current examinations theoretically. The governing equations Reynolds (pressure field), energy (temperature heat conduction field through solids) are coupled solved instantaneously term temperature viscosity. After these set equation pressure is obtained...
