An incredible eradication of thermal indulgence is required to enhance the flow and heat transfer enhancement in micro/nanofluidic devices. In addition, the rapid transport and instantaneous mixing of colloidal suspensions of metallic particles at nanoscale are exceptionally crucial at ascendency of inertial and surface forces. To address these challenges, the present work is intended to investigate the role of trimetallic nanofluid comprising of three kinds of nano-sized granules (titanium oxide, Silica and Aluminium dioxide) with pure blood through a heated micropump in the presence of inclined magnetic field and axially implemented electric field. To ensure rapid mixing in unidirectional flow, the pump internal surface is lined-up with mimetic motile cilia with slip boundary. The embedded cilia whip in pattern due to dynein molecular motion controlled by time and produce a set of metachronal waves along the pump wall. The shooting technique is executed to compute the numerical solution. In a comparative glance it is revealed that the trimetallic nanofluid exhibits 10% higher heat transfer efficiency as compared to bi-hybrid and mono nanofluids. Moreover, the involvement of electroosmosis results in almost 17% decrease in the heat transfer rate if it values jumps from 1 to 5. The fluid temperature in case of trimetallic nanofluid is higher and thus keeps the heat transfer entropy and the total entropy lower. Furthermore, involvement of thermal radiated and momentum slip significantly contribute in reducing heat losses.

Recent studies on fluid flows have shown that the non-Newtonian fluid flows through convergent/divergent channels with heat and mass transport analysis of nanofluids has triggered many researchers because of their occurrence in biomedicine, cavity flow model, flow through canals, and cold drawing operations. Moreover, heat enhancement during fluid flow plays an important role in different engineering applications, which can be achieved by improving fluid thermal physical properties. Therefore, the present study aims at providing a novel mathematical model for non-Newtonian Carreau rheological fluid flow through convergent/divergent channels by employing Buongiorno’s nanofluids model. The governing system of partial differential equations for Carreau fluid flow is formulated via basic conservation laws, for the first time in literature. The dimensionless variables are introduced to get the non-dimensional forms of the governing equations. The resultant system of ordinary differential equtions (ODEs) is numerical integrated using Runge-Kutta Fehlberg method with shooting technique, which is an efficient numerical technique to determine the numerical solutions of ODEs. The varying patterns of non-dimensional velocities, temperature, and concentration fields along with skin-friction, Nesselt and Sherwood numbers are simulated for various eminent physical parameters with converging and diverging walls. The underlying flow physics and thermal behavior are explored in terms of pertinent parameters, for instance, Reynolds number, channel angle, Prandtl number, Brownian motion parameter and thermophoresis parameter. From the present numerical simulations, we have concluded that the Reynolds number has an opposite effect on dimensionless velocity for convergent and divergent channels. It is recognized that the fluid velocity increases with higher values of Weissenberg number for convergent channel. Moreover, the temperature distributions enhance for larger Brownian motion parameter.

The present paper concerned with study the of combined electro-osmotic peristaltic transport with heat and mass transfer which is represented by the Soret and Dufour phenomenon with the presence of the Joule electrothermal heating through a microchannel occupy by Rabinowitsch fluid. The unsteady two-dimensional governing equations for flow with energy and concentration conservation have been formed in a Cartesian coordinate system and the lubrication theory is applied to modify the relevant equations to the problem. The Debye-Hukel linearization approximation is utilizing to modify the electrohydrodynamics problem. The expressions for the axial velocity, the temperature profile, the concentration profile, and the volumetric flow rate are obtained analytically to gain exact solutions, while the numerical integration is used to analyze the pressure rise. The attitude of the Helmholtz-Smoluchowski velocity, the electro-osmotic parameter, the Joule electrothermal heating, the Dufour number, the Soret number, is studied and graphically analyzed. It is showed that the presence of the electric field increased the velocity of the fluid and pressure rise, and it is revealed that the temperature and concentration profile congregate in the center of the channel with increase in the Soret and Dufour number.
