Zusammenfassung:This paper proposes a method for obtaining boiling curve from experimental temperature measurement for an impinging water stream on the moving hot plate without using the inverse method. Using infrared thermography, temperature profiles on the back side of the moving hot metal sheet were measured. On the front side, water impinges on the hot region and induces pre-cooling in the dry region. This experimental setup can be treated as an impinging region of the DC casting. Once the Eulerian steady state is reached, temperature profiles can be approximated as a single curve using Boltzmann function. With this function, energy balance is conducted, including the advection term to obtain the boiling curve. It is observed that the obtained boiling curve is similar to the boiling curve obtained from inverse solution.
