Abstract

Conjugate heat transfer in heat exchangers is at the heart of numerous industrial applications. Topology optimization (TO) is a promising numerical method that allows for the design of high-performance thermo-hydraulic systems from scratch. However, full-scale three-dimensional thermofluidic TO remains largely within the academic sphere and has yet to be easily explored by thermal engineers. To bridge this gap, this paper presents an integrated design workflow tailored for three-dimensional, high-resolution topology optimization of conjugate heat transfer systems, incorporating a mean compliance constraint to ensure structural integrity and load-bearing capability. This is achieved using a dual-mesh approach within the density-based TO framework. We also introduce Tanatloc, a user-friendly graphical user interface developed in JavaScript, which provides versatile functionalities and an interactive experience for thermal engineers. Finally, a 3D printed metal-based prototype is fabricated, and reverse engineering is conducted to reconstruct a CAD model using CT-scan images, paving the way for future experimental investigations.

考虑平均柔度约束的共轭传热三维拓扑优化：向图形用户界面和原型化迈进

热交换器中的共轭传热是许多工业应用的核心。拓扑优化（TO）是一种很有前途的数值方法，它允许从零开始设计高性能的热液系统。然而，全尺寸三维热流体TO仍然主要停留在学术领域，尚未被热工程师轻易探索。为了弥补这一差距，本文提出了一种为共轭传热系统的三维高分辨率拓扑优化量身定制的集成设计工作流程，并结合了平均顺应性约束以确保结构完整性和承载能力。这是在基于密度的TO框架内使用双网格方法实现的。我们还介绍了Tanatloc，这是一个用JavaScript开发的用户友好的图形用户界面，它为热工程师提供了多功能和交互式体验。最后，制作了基于金属的3D打印原型，并进行了逆向工程，利用ct扫描图像重建CAD模型，为未来的实验研究铺平了道路。
