“…measure of the eccentricity and also Brinkman number. It is also noticed that temperature with thermal slip is of greater magnitude than for the no slip case, a pattern which has also been computed by Srinivas et al [29] and Uddin et al [30]. Effectively Br embodies the relative influence of heat produced by viscous dissipation and heat transported by molecular conduction.…”

“…Srinivas et al [29] investigated the effects of heat transfer, magnetic fields and slip condition on peristaltic transport, observing that with great Knudsen number (slip effect), the quantity of trapped boluses is markedly increased. Uddin et al [30] considered thermal, velocity and mass slip effects on bioconvection nanofluid flow with wall transpiration, showing that increased thermal slip decelerates the flow, whereas greater mass (solutal) slip accelerates the flow and also elevates temperatures but suppresses nano-particle concentration.…”

MHD dissipative flow and heat transfer of Casson fluids due to metachronal wave propulsion of beating cilia with thermal and velocity slip effects under an oblique magnetic field

A theoretical investigation of magnetohydrodynamic (MHD) flow and heat transfer of electrically-conducting viscoplastic fluids through a channel is conducted. The robust Casson model is implemented to simulate viscoplastic behavior of fluids. The external magnetic field is oblique to the fluid flow direction. Viscous dissipation effects are included. The flow is controlled by the metachronal wave propagation generated by cilia beating on the inner walls of the channel. The mathematical formulation is based on deformation in longitudinal and transverse velocity components induced by the ciliary beating phenomenon with cilia assumed to follow elliptic trajectories. The model also features velocity and thermal slip boundary conditions. Closed-form solutions to the non-dimensional boundary value problem are obtained under physiological limitations of low Reynolds number and large wavelength. The influence of key hydrodynamic and thermo-physical parameters i.e. Hartmann (magnetic) number, Casson (viscoplastic) fluid parameter, thermal slip parameter and velocity slip parameter on flow characteristics are investigated. A comparative study is also made with Newtonian fluids (corresponding to massive values of plastic viscosity). Stream lines are plotted to visualize trapping phenomenon. The computations reveal that velocity increases with increasing the magnitude of Hartmann number near the channel walls whereas in the core flow region (centre of the channel) significant deceleration is observed. Temperature is elevated with greater Casson parameter, Hartmann number, velocity slip, eccentricity parameter, thermal slip and also Brinkmann (dissipation) number. Furthermore greater Casson parameter is found to elevate the quantity and size of the trapped bolus. In the pumping region, the pressure rise is reduced with greater Hartmann number, velocity slip, and wave number whereas it is enhanced with greater cilia length.

“…Srinivas et al [24] investigated the effects of velocity slip and wall properties on hydromagnetic peristaltic transport with heat transfer. Similar flow problem in a vertical annulus was numerically investigated by Mekheimer and Elmaboud [25].Other relevant work on the combined effects of velocity slip and magnetic field on peristaltic motion of a conducting fluid with heat transfer can be found [26][27][28][29][30][31][32].Bhatti and co-authors The study of non-Newtonian fluids has attracted more attention due to their extensive applications in applied engineering and industry namely extraction of crude oil from petroleum oil products, and syrup drugs and production of plastic materials.…”

We examine the effect of velocity slip on hydromagnetic peristaltic flow of a Casson fluid and heat transfer through an asymmetric channel fluid filled a porous medium.The model governing equations are obtained, simplified using long wavelength and low Reynolds number assumptions and then tackled analytically.Numerical result for effects of embedded parameters on the stream function, axial velocity, pressure drop, temperature, skin friction and Nusselt number are presented graphically and discussed. It is found that thepermeability parameter enhances the size of the trapped bolus while velocity slip diminishes it. A rise in magnetic field intensity and Cason fluid parameters decrease the both velocity and temperature profiles.The present problem is of substantial importance in crude oil refinement and biomedical engineering.

“…The study of flow through the channels with the slip is applied in chemical engineering, e.g., two phase flows in bearings of porous slides, flow through pipes in which reactions occur at the wall, etc. Srinivas et al [16] considered the MHD peristaltic motion to investigate the slip wall property and also the heat transfer effect. Das [17] considered the collective effect of the slip wall, MHD and transfer of heat on the Maxwell fluid flowing through a peristaltic porous medium channel.…”

An attempt has been made to examine the effects of magnetohydrodynamic couple stress fluid in peristaltic flow with porous medium under the impact of slip, heat transfer and wall properties. The expressions are obtained for temperature, coefficient of heat transfer and velocity. Influences of different parameters, the Hartmann number, Brinkman number and adaptability parameters on the temperature and warmth trade coefficient are discussed through outlines.
