In this paper, a numerical analysis of forced convection heat transfer from 3D protruding heaters mounted on an adiabatic substrate of a horizontal rectangular channel was performed using the ANSYS/Fluent 15.0 software. A uniform heat generation rate was assumed in the protruding heaters and the cooling was performed by means of a forced airflow with constant properties in the laminar regime under steady state conditions. At the channel entrance the flow velocity and temperature profiles were assumed uniform. The governing equations with the respective boundary conditions were solved numerically within a single domain through a coupled procedure using the control volumes method.
