Two separate types of multiphase flow models have been developed theoretically in this paper. Fourth-grade fluid model of non-Newtonian in nature is considered the main carrier. Silver and gold metallic particles of spherical shape suspend to form highly viscous multiphase flows which drift through an inclined channel. Effects of magnetic fields acting across the channel are applied as the body force. An approximate solution for the nonlinear flow dynamics of the two-phase suspensions. A comprehensive parametric study is performed to graphs against the pertinent parameters. Further, the obtained mathematical results and visual evidence are validated through computational data and found to be in completer agreement. It is inferred that gold multiphase suspensions can effectively be used in chemical and coating processes.
