“…Experimental investigations and theoretical analyses have been conducted to determine the fundamental wetting characteristics of thin liquid films on the outer surfaces of heated rods, horizontal surfaces of flat plates and the inner surfaces of heated tubes (Chan, 1994;Ma et al, 1998;Ma and Peterson, 1997;Peng and Peterson, 1992;Pratt and Hallinan, 1997;Wayner, 1994). The evaporating thin film profile within a heated conduit or channel at the capillary scale also depends on surface heat flux.…”
