Abstract
Abstract 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.
