The problem is considered on mixed convection flow due to the effect of small amplitude oscillations of a viscous\nincompressible fluid along a horizontal circular cylinder. Direct implicit finite-difference scheme is employed to\nsolve the dimensionless system of partial differential equations. In case of steady flow, the solutions are presented\nas functions of the curvature parameter X on the entire surface of the cylinder and there is a visual comparison with\nthe existing result. For fluctuating flow, considering Prandtl number, Pr=1.0, the results are shown graphically in\nterms of amplitude and phase of the Nusselt number for different values of buoyancy parameter Ã?». Due to the effect\nof Ã?» and frequency parameter Ãâ?°, streamlines and isotherms as well as transient shear stress and heat transfer are\nillustrated in the interplay of study.
