Combined forced and natural convection heat transfer from upward-faceing horizontal heated flat plate is nodeled by phenomenological method modifying natural convection heat transfer model at high layer. In this model, mixed or pure natural convection heat transfer coefficient is estimated as averaged one. In the model new boundary layer is assumed to start its growth from a position that previous layer finishes by releasing hot fluid plume "Thermal", and vanishes again at a point where a certain critical condition is satisfied. This theory can explain the transitional phenomena from pure forced convection to pure natural convection through mixed convection. The varidity of the theory is confirmed by experiment using upward-faceing horizontal heated flat plate.
