Influence of Jet Velocities and Material Properties in Quenching of Metal with Array of Jets

Abstract:

In this research work, the influence of jet velocities and different kind of metals during the quenching process with the use of array of jets was tested. Three different jet velocities i.e. 0.9m/s, 1.2m/s, and 1.8m/s were applied for the quenching of copper K12. Experiments with different kind of metals are using AA6082, Nickel, and Copper K12 samples. The influence of jet velocities and material properties was characterized by figuring out the trend of propagation of Leidenfrost Point (LFP) and maximum Heat Flux (maxHF) point over time. In addition, Leidenfrost Temperature (LFT), maxHF values with the corresponding DNB temperature as well as the width of wetting front over position were also presented. The results show that the jet velocities and the material properties significantly influence the boiling characteristics in a metal quenching process with array of jets.
