Liquid-vapor phase transitions in wet cutting simulations

Enhancement of a finite pointset method (FPM) based wet cutting simulation are achieved by two measures in this study. Firstly, an experimental determination of the heat transfer coefficient (HTC) is performed by jet cooling a hot plate and using the resulting temperature field for three-dimensional inverse heat conduction simulation. Following the subsequent integration of the HTC into the cutting simulation, the second measure involves the implementation of a temperature-dependent coolant phase transition functionality which allows the modelling of evaporation. The final analyses carried out with the resulting cutting simulation model show the local distribution of coolant vapor around the chip.
