Cattaneo–Christov heat flux model for heat transfer of Marangoni boundary layer flow in a copper–water nanofluid

摘要: The Cattaneo–Christov heat flux is first utilized to explore the transfer characteristics of Marangoni boundary layer flow in a copper–water nanofluid. driven by exponential temperature. Five different types nanoparticle shapes including sphere, hexahedron, tetrahedron, column and lamina are considered for nonlinear system partial differential equations reduced similarity transformations then solved numerically shooting method. It found that sphere has better enhancement than other both temperature thickness thermal lower model classical Fourier's law conduction.
