Quench and re-wetting temperatures were measured upon jet quenching of hot cylindrical tubes. Correlations have been developed and provided good fit of data. Quench and re-wetting temperatures were found to greatly depend on water subcooling. Stagnation point showed higher quench and re-wetting temperatures than other locations. Quench temperature decreased by increasing surface curvature and tube conductivity. Re-wetting temperature is a weak function of both variables.
