Abstract In this effort, solid hybrid nanofluid flowing and thermal transport characteristics over a slippery, nonlinear, uniform stretching surface are proposed. The influence of nanosolid particle shapes, permeability material, viscous dissipative flow, Cattaneo-Christov heat flux and radiate flux are studied. The predominant flow equations are systemized in form of partial-differential equations (PDEs). Keller-box's computational method is the employed method to identify the self-similar resolution for transformed principles into the ordinary-differential equations (ODEs) by appropriate transmutations. Williamson hybrid nanofluidcontaining of dual varied types of nanoparticles, named Copper ( C u ) and Zirconium dioxide ( Z r O 2 ) in the rich viscid; based fluid of kind E O - Engine Oil is utilized in this research. The remarkable consequence of this analysis is reached by comparison of thermal transmission level of such type of fluid ( Z r O 2 − C u / E O ) , which has increasingly more gains to traditional nanofluids ( C u − E O ) . The lamina-figured elements effect the utmost major thermal conductivity in the boundary-layer, whilst the lowermost thermal conductivity is detected in sphere geometric nanoparticle.
