We have already studied droplet vaporization on a hot surface with flame-sprayed ceramic coating at atmospheric pressure. The present study extended the earlier work and experiment were carried out at pressures up to 10 MPa. The vaporization behavior of the droplet in the pressure vessel prepared for optical observation was investigated, and lifetime curves for some pure liquids were measured. The result showed that the ceramic-coated surface had a wide temperature range in which nucleate boiling was observed in the spreading liquid, and the droplet vaporized in quite a short time at any subcritical ambient pressure. The lifetimes in this region depended on pressure, and the optimum pressure yielding the minimum lifetime was found.
