Analysis of Reciprocal Thermal Conductivity on Free Convection Flow along a Wavy Vertical Surface

The effects of thermal conductivity which depend on temperature are conversely proportional with the linear function free convective flow where fluid is viscous and incompressible along a heated uniform vertical wavy surface has been examined in this study. boundary layer equations associated conditions that govern converted into nondimensional form by using an appropriate transformation. In domain plate flat, resulting method nonlinear PDEs mapped then worked out numerically applying implicit central finite difference technique Newton’s quasilinearization method, block Thomas algorithm well known as Keller-box method. outputs obtained terms heat transferring rate, frictional coefficient skin, isotherms, streamlines. outcomes showed local skin friction coefficient, temperature, velocity all decreasing, both become narrower rising values reciprocal variation temperature-dependent conductivity. On other hand, velocity, decrease 43% 64%, respectively, but transfer rate increases 61% approximately, thinner when Prandtl number increases.
