Abstract This article discloses a comparative analysis for convective movement of Williamson liquid by a cylinder and sheet. Heat transport mechanism is employed for sheet and cylinder via extra heat factors, convective condition, viscous dissipation, Joule heating and heat source. Concentration is regulated through auto-catalyst and reactant species. Keller box method is used for numerical outcomes to the obtained ordinary differential equations. Impacts of relevant variables of interest are graphically discussed. The findings reflect that movement of liquid and concentration are prominent by cylinder than sheet. Interestingly the contrary trend is observed for temperature. Skin friction is comparatively larger for cylinder than flat sheet. Nusselt number also holds observation similar to skin friction. Skin friction is decreased for larger Weissenberg number. Prandtl, Biot and curvature variables boost the heat transfer rate whereas Eckert and heat source variables show opposite trend.
