Abstract: The objectives of the described colloidal model are to analyze the heat transfer in SWCNTs-H2O and MWCNTs-H2O nanofluid flow over a curved stretchable semi-infinite region by contemplating the role of thermal jump and velocity slip. The self-similar time dependent model is formulated via feasible similarity transformations. After the successful formulation, model is handled via RK scheme joined with shooting technique. Impact of emerging flow parameters in the nanofluids velocity and heat transfer discussed comprehensively and found fascinating results. Moreover, flow pattern is plotted and stimulations of volumetric fraction on thermophysical characteristics of SWCNTs and MWCNTs are explored via bar charts. It is noted that the temperature drops slowly for SWCNTs-H2O nanofluid. The volumetric fraction affects the thermal conductance positively and dominant behavior is examined for SWCNTs. The heat transfer increases promptly for larger curvature. A comparative analysis is provided under certain assumptions which shows the reliability of the presented analysis.
