Kurzbeschreibung (Abstract)

The focus of this study is on the heat flux during cooling of a hot substrate by an impacting monodisperse drop train. Such a drop train is used for achieving high heat flux densities over small surfaces. The temperature inside the substrate is measured with high temporal and spatial resolution using thermocouples. Furthermore, a new analytical model has been developed to describe and predict the transient cooling and temperature of a semi-infinite body by the impacting drop train, assuming a single point heat sink on the surface. The experimental data agree very well with the theoretical predictions for various drop train frequencies.
