Abstract Nanomaterial is a new kind of heat transport medium, comprising nanoparticles (1–100 nm) which are homogeneously and stably dispersed in continuous phase liquid. These dispersed nanoparticles, generally a metal or metal oxide significantly improve the thermal performance of the nanomaterial, enhances convection and conduction coefficients, allowing for more heat transport. The current communication models the flow of Jeffrey nanomaterial subject to variable thicked surface. The surface is convectively heated. Joule heating, convective boundary conditions and nonlinear radiative heat flux are taken into account. Equal strengths of diffusion coefficients are considered for homogeneous and heterogeneous reactions. Boundary layer concept leads to mathematical modeling. Suitable transformations are implemented to convert the nonlinear systems to ordinary ones. Series solutions are achieved through the HAM technique. Physical importance of emerging parameters is addressed through graphical sketch. We explored that temperature is increased for higher values of radiative heat flux and Eckert number. Keywords Jeffrey nanomaterial · Variable thicked surface · Entropy generation · Homogeneous–heterogeneous reactions · Nonlinear radiative heat flux and Joule heating · Convective boundary conditions

Many industrial and mechanical processes comprise the transport of heat energy. During any mechanical or industrial facility, heat must be removed, added or moved from one process to another and studying this has turned into a noteworthy assignment for mechanical necessity. These processes provide a source of energy recuperation and the process of liquid cooling/heating. There are numerous techniques to enhance the heat transport effectiveness. A few techniques are use of extended surfaces, utilization of vibration of the heat transport surfaces an
