Heatline visualization of MHD natural convection heat transfer of nanofluid in a prismatic enclosure

Abstract Temperature transfer by virtue of natural convection for visualizing heat transport characteristics through heatline method within a prismatic cavity filled with Cu-H2O nanofluid considering two different temperature boundary conditions is performed numerically. Two top inclined walls are w...
