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
and Zirconium dioxide () in the rich viscid; based fluid of kind - 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, which has increasingly more gains to traditional nanofluids. 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.
