ABSTRACT The application of inclined surface flow characteristics in the context of Williamson tri‐hybrid nanofluidswith consideration of Soret and Dufour effects, has broad implications across multiple industries including heat exchangers, solar energy systems, aerospace engineering, and manufacturing processes. These insights can drive advancements in thermal management, energy efficiency, and overall system performance. Hence, in this study, we explore the entropy generation rate within a flow of bio‐convection of a magneto hydrodynamic (MHD) Williamson tri‐hybrid nanofluid past an inclined stretching surface. The ongoing research aims to develop an approximate solution for the tri‐hybrid nanofluids, consisting of copper (Cu), aluminum oxide (), and molybdenum disulfide (), when mixed with a liquid based on ethylene glycol (). Further, the consequences of thermal radiation, joule heating, heat source, chemical reactions, and viscous dissipation are anticipated. The bvp4c solver method is used to numerically solve the coupled partial differential equations after they have been converted into nonlinear ordinary differential equations via similarity variables. Several important conclusions are drawn from our investigation into the upshots of different thermophysical factors on the flow field. According to perception, growth in the Williamson parameter leads to a reduction in liquid motion for both ternary and unary nanofluids. Moreover, an increase in the Dufour and Soret numbers decreases the temperature and concentration profiles, respectively. The current outcomes are obtainable for confirmation in line with previous studies.
