Heat transfer simulation of a cryogenic cooling stream in machining operation

This paper introduces a generic model for predicting the heat transfer during cryogenic cooling in machining processes in a comprehensive way. The model is based on a flow of coolant over a hot surface that is dominated by the Leidenfrost effect. To get an overall description of the problem, it is essential not only to consider the gas phase, but also the interaction between gas and liquid as well as the evaporation process. Therefore, the...
