In the present study, the fundamental model for interfacial heat transfer coefficient (IHTC) in high-pressure die-casting (HPDC) developed by Hamasaiid et al . is re-examined using numerical simulations and established literature. The role of impact pressure on the peak IHTC is re-evaluated for the Aluminum alloy Al-9Si-3Cu and the magnesium alloy AZ91D. Currently, ANSYS FLUENT does not have a mesh independent model for air gap evolution at the die-casting boundary. To address this, an implementation of the Hamasaiid model is built for ANSYS FLUENT 18.1 and its results are compared to experimental work. All the derivations and code for the simulations are offered as open source under the GNU General Public License v3.0.

高压压铸中界面传热系数基本模型的评估和实施

在本研究中，Hamasaiid 等人开发的高压压铸 (HPDC) 界面传热系数 (IHTC) 基本模型。使用数值模拟和既定文献重新检查。对铝合金 Al-9Si-3Cu 和镁合金 AZ91D 重新评估了冲击压力对峰值 IHTC 的作用。目前，ANSYS FLUENT 没有用于压铸边界气隙演化的网格独立模型。为了解决这个问题，为 ANSYS FLUENT 18.1 构建了 Hamasaiid 模型的实现，并将其结果与实验工作进行了比较。模拟的所有派生和代码都是在 GNU 通用公共许可证 v3.0 下作为开源提供的。
