An exponential space dependent heat source (ESHS) process is implemented to examine the thermal transport characteristics. Additionally nanoparticles mass flux condition is considered. The solutions are numerically computed. Impacts of various physical variables appearing in the solutions of non-linear systems are carefully analyzed. The current work identifies that temperature distribution of nanoliquid enhances for higher values of thermophoresis and Brownian motion variables. Moreover activation energy and temperature difference parameters diminish the nanoparticles concentration. Comparative study is provided in order to validate our outcomes. https://scientiairanica.sharif.edu/article_21995_0102fc6f429d00d7fc168ed2bf527238.pdf
