Abstract In present study the impacts of thermal radiation and Joule heating for MHD peristaltic motion of fourth-grade nanoliquid in a channel are addressed. Elastic characteristics of channel walls are studied. Velocity, concentration and thermal slip effects are imposed. Furthermore the influences of viscous dissipation, heat source /sink and chemical reaction in modelling are retained. Nanofluid model consisting of thermophoresis and Brownian motion is employed. Mathematical formulation is developed by adopting long wave length and low Reynolds number. Numerical technique is used for finding the solutions of the governing problem. Comprehensive study of emerging flow variables for velocity, temperature, concentration of nanoparticles, heat transfer coefficient and trapping is addressed graphically. Moreover the results for skin friction coefficient and Sherwood number are also examined.
