The present work investigates mass and heat transport in non-Newtonian Sisko fluid past a three-dimensional bi-directional stretched heated surface with MHD effect, heat radiation, Joule warming, variable thermic conductivity, and temperature-dependent diffusivity. Comprehension the intricate relationships amongst mass and heat transfer in Sisko fluid across various magnetic field and radiation conditions requires an understanding of this model. It offers information on how to best optimize industrial operations where controlling fluid behavior and thermal characteristics is crucial, such as cooling systems and polymer extrusion. The difficulty is derived from resembling coupled nonlinear PDEs by engaging boundary layer theory and transforming them into systems of ODEs by applying suitable similarity transformations. The nonlinear converted ODEs have been solved using OHAT (optimal homotopy analysis technique) and the results are presented via graphs and tables. The performed analysis shows that escalating values of fluid parameter shows shear-thinning behavior and as a result fluid velocity upsurges. It is observed through findings that the velocity spectrum strengthens along the x-axis and y-axis concerning the Sisko fluid factor ( A ) . The thermal appearance exhibits improved behavior with higher thermal conductivity ( ε ) levels. Moreover, the thermal profile indicates enhanced behavior given the enrichment in Eckert number Ec and Radiation factor R . Previous research indicates that no comprehensive studies have been carried out to examine mass, heat transfer with changing thermal conductivity, diffusive coefficient variation, radiation warmth, and Joule heating for the two-way extended transport of the Sisko nanofluid. This study fills up that void.
