摘要：

The effect of inclination angle of the downward facing flat plate on the interfacial wavy motion is investigated utilizing the water test apparatus DELTA FS (Downward Ebullient Laminar Transition Apparatus Flat Surface) in a quasi-steady state. Film boiling heat transfer coefficients are obtained on the relatively long surface in the flow direction. The measured heat transfer coefficients are compared with those predicted by the laminar film boiling and interfacial wavy film boiling correlations at the same experimental condition. Visualization of the vapor film revealed that the interfacial wavelength decreases as the flat plate moves from the vertical to downward facing locations.
