抄録

An experimental study concerned with the effect of surface roughness of a ceramic-coated surface on droplet vaporization was performed. Test surfaces used were almost identical in surface structure except for the surface roughness. Lifetime curves for several combinations of pure liquid and the hot surface with coating having different roughnesses were measured at surface temperatures up to 1 100 k by a high-speed video optical system. we also observed in detail the vaporization behavior using a 16 mm high-speed motion-picture camera, especially in the rapid vaporization region. The result showed that the higher the surface roughness was, the wider the temperature range yielding the short lifetimes became. In this temperature range, slightly reduced lifetimes caused by the surface roughness were obtained in some cases.
