In this paper, laminar forced convection heat transfer of a copper–water nanofluid inside an
isothermally heated microchannel is studied numerically. An Eulerian two-fluid model is
considered to simulate the nanofluid flow inside the microchannel and the governing mass,
momentum and energy equations for both phases are solved using the finite volume
method. For the first time, the detailed study of the relative velocity and temperature of the
phases are presented and it has been observed that the relative velocity and temperature …
