Numerical software used to predict material properties during the quenching process rely heavily on surface heat transfer rates based on input heat transfer coefficients (HTC) typically derived from empirical relationships or inversing techniques. The accuracy of these values are one of the most important factors controlling the quality of the material property predictions. This paper discusses a method for accurately measuring heat transfer rates seen in industrial oil quenching operations over a variety of quench tank conditions with the goal of providing better quality heat transfer information to material property prediction software. The design of an experimental fixture for measuring pseudo steady state boiling heat transfer rates on a 2 × 2 heated surface is discussed. Numerous experimental data sets collected by the experimental fixture are shown followed by a narrative review of the trends observed in the measured heat flux data. The development of a Computational Fluid Dynamic (CFD) model based on the boiling heat flux data collected by the testing fixture is discussed. Simulation predictions for two different parts is reviewed. This review discusses the experimentally measured time temperature thermocouple data collected during the quenching operations and compares these data to the numerical predictions of the CFD simulation. The CFD predicted HTCs are then compared to HTC values determined by the standard inversing technique frequently used to determine HTC values used as input to material modeling software.
