Abstract

This paper presents a Computational Fluid Dynamics (CFD) simulation of the quenching process based on ISO 9950, focusing on the heat flux and heat transfer coefficient integrated over a metal specimen. The numerical method, which employs the two-fluid VOF method and frozen turbulence approach (Cukrov et al., Appl. Sci. 2023, 13, 9144), is used for the transient simulation. Since quenching processes involve complex boiling phenomena shifting from film boiling to nucleate boiling, a standard method based on VOF cannot be applied. The comparison of the simulation results with the ones obtained using correlation, and the data obtained using the Inverse Heat Transfer Analysis (IHTA) method have revealed that the proposed method can accurately predict the heat flux and heat transfer coefficient in the film boiling regime of the immersion quenching process. Note that the previous paper (Cukrov et al., Energies. 2023, 16, 7926.) presented the immersion process modeling and the temperature distribution, while the current paper examines the heat transfer characteristics of the immersion quenching process.

使用欧拉双流体方法对浸入式淬火过程中的薄膜沸腾传热进行数值模拟

本文介绍了基于 ISO 9950 的淬火过程计算流体动力学（CFD）模拟，重点是金属试样上的热通量和传热系数综合。数值方法采用了双流体 VOF 法和冻结湍流法（Cukrov 等人，《应用科学》2023 年第 13 期，9144），用于瞬态模拟。由于淬火过程涉及从膜沸腾到核沸腾的复杂沸腾现象，因此不能采用基于 VOF 的标准方法。将模拟结果与使用相关性方法获得的结果以及使用逆传热分析（IHTA）方法获得的数据进行比较后发现，所提出的方法可以准确预测浸入式淬火过程中膜沸腾状态下的热通量和传热系数。需要注意的是，前一篇论文（Cukrov 等人，Energies.

期刊介绍： Case Studies in Thermal Engineering provides a forum for the rapid publication of short, structured Case Studies in Thermal Engineering and related Short Communications. It provides an essential compendium of case studies for researchers and practitioners in the field of thermal engineering and others who are interested in aspects of thermal engineering cases that could affect other engineering processes. The journal not only publishes new and novel case studies, but also provides a forum for the publication of high quality descriptions of classic thermal engineering problems. The scope of the journal includes case studies of thermal engineering problems in components, devices and systems using existing experimental and numerical techniques in the areas of mechanical, aerospace, chemical, medical, thermal management for electronics, heat exchangers, regeneration, solar thermal energy, thermal storage, building energy conservation, and power generation. Case studies of thermal problems in other areas will also be considered.
