The discussed project aims at developing a physical-mathematical model for thermal hydraulic phenomena that occur in the process of spray cooling of the forging die. Underlying physical processes will be observed and characterized using two experimental setups: The first setup will be used to characterize the impact of the single drop onto a hot substrate, whereas the second setup will be used to observe spray impact. Working fluid will represent a mixture of lubricants with water, whereas the existing experience obtained within the framework of the subproject C04 of SFB-TRR 75 with the use of pure water will be used and extended. Gained experimental data will be used to develop a numerical model of spray cooling which will be used to optimize the industrial use of spray cooling of the forging die.
