We studied the impact of magnetic field and chemical reaction on the peristaltic motion of nanofluid in the horizontal asymmetric channel with heat and mass transfer in this paper. The unsteady governing equations of the present problem were formulated. After the unsteady equations are transformed to steady and then the implementation of lubrication theory approximation, the lengthy equations are shortened. The coupled nonlinear differential equations (temperature and concentration equations) are analytically solved using the perturbation method. The exact analytical solution of the stream function was also calculated.The results of the velocity profile, pressure rise, temperature, and concentration are plotted through the MATLAB software and the streamlines are drawn through the MATHEMATICA software. The impact of key fluid parameters is discussed using graphical results. One observes that, for large values of the thermophoresis parameter, the temperature of the fluid increases, and more energy is produced.

Purpose The purpose of this paper is to investigate the behavior of a non-Newtonian nanofluid caused by peristaltic waves along an asymmetric channel. Additionally considered is the production of thermal radiation and activation energy. Design/methodology/approach The equations of momentum, mass and temperature of Sutterby nanofluids are obtained for long wavelength. By taking into account the velocity, temperature and concentration, the formulation is further finished. Findings Analyses of the physical variables influencing flow features are represented graphically. The present investigation shows that an enhancement in the temperature ratio parameter results in an increase in both the temperature and concentration. The investigation also shows that the dimensionless reaction rate significantly raises the kinetic energy of the reactant, which permits more particle collisions and as a result, raises the temperature field. Originality/value Due to their importance in the treatment of cancer, activation energy and thermal radiation as a route of heat transfer are crucial and exciting phenomena for researchers. So, the cancer cells are killed, and tumors are reduced in size with heat and making hyperthermia therapy a cutting-edge cancer treatment.

This article aims to investigate the electro-osmotic flow of the Eyring-Powell nanofluid under the peristaltic mechanism with the influence of the porous medium in the micro-channel. The modified system is applied externally to an electrical field in the horizontal direction and a magnetic field in the transverse direction. Governing equations of nanofluid flow are formulated, and the assumptions of low Reynolds number and large wavelength approximations are tackled. The resulting coupled non-linear partial differential equations like velocity and temperature equations are solved numerically by the NDSolve command using the computational mathematical software Mathematica. The influence of various important parameters on the velocity of the fluid, the temperature profiles, and the trapping phenomenon are discussed in detail by graphs. Under the influence of Joule heating, the study details the thermal transport process in the fluid. It demonstrates how an increase may significantly improve the momentum transmission in the core region of the microchannel in the volume fraction of the nanoparticles in the fluid.
