Abstract
This study addresses CuO -TiO2/CMC-water hybridnano-liquid in the influence of mixed convection flow and thermal radiative flow past a stretchable vertical surface. Cross nano -fluid containing Titanium dioxide (TiO2); and Copper Oxide (CuO) are scattered in a base fluid of kind CMC water. In addition, theirreversibility analysis is also examined in the current problem. A suitable transformation is utilized to transmute the momentum and thermal mathematical expres-sion in non-dimensionless form. Further, the BVP utilizer is set to solve these mathematical expres-sions. The significance of leading variables on the velocity, entropy generation,temperature, and Bejan numberare displayed and elaborated through the aid ofgraphs. The outcomes demonstrate that the larger values of the Weissenberg number reduce the velocity and entropy profiles while escalatingthe temperature distribution and Bejan number. The drag friction and heat transfer rate are enhanced by exceeding the value of the mixed convective parameter and Biot number. The motive of this manuscript is to give more interest of entropy production study with heat and fluid flow on Cross fluid with nanoparticles and base fluid to develop the system performance. The cur-rent work is existed with the previous literaure and obtain a fantastic achievement.(c) 2022 THE AUTHORS. Published by Elsevier BV on behalf of Faculty of Engineering, Alexandria University.
