摘要：Analysis are made to find the heat transfer characteristics and skin friction for two-dimensional oblique stagnation point flow of SWCNTs and MWCNTs based nanofluid flowing over a curved surface. Similarity transformations convert the governing flow field equations into a pair of non-linear ordinary differential equations, and then they are numerically solved through bvp4c function in MATLAB. The inspection of the obtained result reveals that SWCNTs based nanofluid have comparatively higher rate of heat transfer and skin friction then MWCNTs based nanofluid, which are due to their dissimilar values of densities. Moreover, in the case of flat surface (K = ∞) maximum amount of heat is transferred compared to the curved surface. The velocity distribution tends to decrease as we approach from curved to flat surface. Further, the Nusselt number provides higher values for SWCNTs case when solid fraction of nanoparticles enhances. Finally, the comparison of the current numerical results with the published literature in a limiting case is given and found to be in an excellent agreement.
