“…The pressure drop and the volumetric interphase heat Besides the mechanical properties, the investigation of the heat and mass transfer performances of a TPMS is also relevant. The numerical simulation of the heat and mass transfers for this type of engineered metal foam is reported in [46], where the analysis of the thermal entrance region in a gyroid TPMS based channel is carried out. The flow model employed for the local momentum balance equation is based on the Navier-Stokes equations while, for the local energy balance, it is based on a convection/conduction equation.…”

The use of innovative methods for the design of heating, cooling, and heat storage devices has been mainly oriented in the last decade toward the use of nanofluids, metal foams coupled with working fluids, or phase change materials (PCMs). A network of nine Italian universities achieved significant results and innovative ideas on these topics by developing a collaborative project in the last four years, where different approaches and investigation techniques were synergically employed. They evaluated the quantitative extent of the enhancement in the heat transfer and thermal performance of a heat exchanger or thermal energy storage system with the combined use of nanofluids, metal foams, and PCMs. The different facets of this broad research program are surveyed in this article. Special focus is given to the comparison between the mesoscopic to macroscopic modeling of heat transfer in metal foams and nanofluids, as well as to the experimental data collected and processed in the development of the research.

“…In paper [114], the influence of the TPMS on heat transfer and water flow resistance in the structure of the sheet gyroid that was 2 × 2 × 10 (10 × 10 × 50 mm) was numerically investigated. StarCCM+ 2019.2 software and the volume-averaged model were adopted to solve the momentum and energy transfer.…”

Review of the State-of-the-Art Uses of Minimal Surfaces in Heat Transfer

The design of heat exchangers may change dramatically through the use of additive manufacturing (AM). Additive manufacturing, colloquially known as 3D printing, enables the production of monolithic metal bodies, devoid of contact resistance. The small volume of the exchanger, its lightness of weight, and the reduction of its production costs, compared to conventional methods, make the production of heat exchangers by AM methods conventional technologies. The review study presents a new look at the TPMS as a promising type of developed surface that can be used in the area of heat transfer. (Thus far, the only attractive option. The most important feature of additive manufacturing is the ability to print the geometry of theoretically any topography. Such a topography can be a minimal surface or its extended version—triply periodic minimal surface (TPMS). It was practically impossible to manufacture a TPMS-based heat exchanger with the method of producing a TPMS.) The issues related to the methods of additive manufacturing of metal products and the cycle of object preparation for printing were discussed, and the available publications presenting the results of CFD simulations and experimental tests of heat exchangers containing a TPMS in their construction were widely discussed. It has been noticed that the study of thermal-flow heat transfer with the use of TPMSs is a new area of research, and the number of publications in this field is very limited. The few data (mainly CFD simulations) show that the use of TPMSs causes, on the one hand, a several-fold increase in the number of Nu, and on the other hand, an increase in flow resistance. The use of TPMSs in heat exchangers can reduce their size by 60%. It is concluded that research should be carried out in order to optimize the size of the TPMS structure and its porosity so that the gains from the improved heat transfer compensate for the energy expenditure on the transport of the working fluid. It has been noticed that among the numerous types of TPMSs available for the construction of heat exchangers, practically, four types have been used thus far: primitive, gyroid, I-WP, and diamond. At the moment, the diamond structure seems to be the most promising in terms of its use in the construction of heat exchangers and heat sinks. It is required to conduct experimental research to verify the results of the CFD simulation.

“…Modeling and simulation have been used commonly for the study of cellular metals. These types of computational tools have generally been led toward the study of their mechanical [32] or physical properties [33], with few reports related to their use in their manufacturing. Most research are concentrated on closed-pore foams processing, on topics such as bubble decay analysis, bubble expansion, and foam solidification obtained with foaming agent [34][35][36].…”

In this work, processes such as additive digital manufacturing (ADM) and precision casting are presented as alternative methods to manufacture aluminum foams with ordered open-pore morphology. Digital modeling of cellular structures with defined regular patterns was manufactured with ABS and wax and then melted in aluminum A356 alloy by a replication casting process. To guarantee the complete filling of the mold, a simulation by the Flow-3D program was made. This computational tool allowed to determine the temperature values of both melting and the mold temperature. The simulations revealed potential defects in the metal foams to be obtained, which were evidenced by the cast pieces processed after as a validation test. The results show that the casting process carried out supported by a computational fluid dynamics (CFD) simulation allows understanding the effects of the simulated parameter process, optimizing the parameters involved in the infiltration process, and establishing the conditions for obtaining a sound piece of open-cell aluminum foam with truncated octahedron pores shape. The established manufacturing process conditions can be used to produce lattice structures with multifunctional uses such as impact and blast-proof devices, vibration attenuators, or where enhancement of heat transfer could be needed.
