210 Effect of scale on nucleate pool boiling
Details
A series of experiments on the nucleate pool boiling was performed by the use of platinum wires with scale. The heat resistance of scale was measured by the forced convection method. As a result of the experiments, the more vigorous bubbling on the scale platinum wire surface was observed compared to that on the bare platinum wire surface at the same heat flux, the boiling curve on the scale surface shifted to the right side of that on the bare suface and the boiling curve corrected with the heat resistance of scale approached that on the bare surface at the high heat flux region. The scale surface didn't enhance the boiling heat transfer though the bubbling was more vigorous than that on the bare surface.
