“…Castro et al [33] delved into the design of radiative enclosures using a solid isotropic material with penalization (SIMP) approach to redistribute reflective material. In this framework, 2D element density variables were exploited to interpolate the surface reflectivity inside the enclosure, allowing the determination of temperature and heat flux fields.…”

This study applies multi-physics concurrent multiscale topology optimization to develop a lightweight porous linear actuation mechanism activated by laser energy. It meticulously explores thermal dissipation mechanisms, incorporating conduction, convection, and radiation dynamics. By examining various numerical cases, the study reveals a substantial 45% performance improvement in porous designs compared to solid actuators. The investigation extends to simultaneous optimization of multiscale porous displacement actuators, achieving a remarkable 75% weight reduction and demonstrating significant performance enhancements over single-scale designs. The increased freedom in micro-scale design allows more efficient material distribution, optimizing both macro and overall layouts. Sequential optimization of macro and micro-scale actuators is contrasted with concurrent multiscale optimization, showing inferior performance for separate optimizations. The study also delves into topology optimization under energy dissipation, focusing on multiple-rate thermal convection and revealing adaptive design behaviors in response to thermal stresses. Macro-scale designs influenced by convection exhibit perpendicular links and adaptive microstructures to enhance resilience and elasticity. The investigation also includes thermal radiation and convection, highlighting intricate design considerations for effective thermal dissipation. Ultimately, this study advances the understanding of multiscale effects in topology optimization, paving the way for more efficient and lightweight laser-activated porous actuators.

“…The design using topology optimization, manufacturing and subsequent experimental testing of optimized heat sinks was presented for a forced convection 2D Stokes flow thermofluid model [28] and a 2D air-cooled heat sink model considering conduction and side surface convection [34]. Castro et al [35] use the topology optimization method to design enclosures in which radiation is the dominant heat transfer mechanism. For a more detailed description of the literature on thermal and thermofluid topology optimization, the reader is referred to a very recently published review paper on this topic [36].…”

In this work, density-based topology optimization is applied to the design of the air-side surface of dry-cooled power plant condensers. A topology optimization model assuming a steady-state, thermally and fluid dynamically fully developed internal flow is developed and used for this application. The conductance of the heat exchanger is maximized for a prescribed pressure drop and prescribed air-side temperature change across the heat exchanger. Polymer with infilled thermally conducting metal filaments is considered as the heat exchanger material which allows cost effective additive manufacturing techniques to be used to fabricate the obtained designs. Parametric studies are presented that analyze the effect of the material thermal conductivity and the heat exchanger unit cell height on the system's performance. The designs obtained from topology optimization are benchmarked against a simple optimized slot channel model in order to demonstrate the superior performance of the topology optimized designs. Thus, this work demonstrates the usefulness of topology optimization to fully exploit the design freedom afforded by additive manufacturing technologies.
