“…Actually, many studies have shown that some ultracomplex structures have obvious benecial effects on mass and heat transfer efficiency. 258,280,281 Therefore, the inuence of complex shapes can be further studied through the 3D printing technique, and more scale-up experiments should be carried out. Besides, more simulations of gas ow distribution are also needed to guide the scaled-up adsorptive gas separation process design.…”

In this study, a computational fluid dynamics (CFD) model is employed to examine the feasibility of utilizing corrugated polymer-based heat exchangers for low-temperature applications. The k-ω Shear Stress Transport (SST) turbulence model is implemented for simulating turbulent fluid flow within the flow channels in cases with corrugations and varying Reynolds numbers, while a laminar model is applied for the flat heat exchanger cases. The simulations reveal that, under specific conditions, polymer-based heat exchangers exhibit effective heat transfer performance for low-temperature applications. When the heat exchanger's polymer surface thickness is less than 2.7 mm and possesses corrugations, its heat transfer efficiency surpasses that of flat aluminum heat exchangers with the same thickness. Furthermore, the analysis of the thermal-hydraulic performance demonstrates that incorporating small, widely-spaced corrugations on the heat exchanger surface yields optimal heat transfer relative to the increase in pumping power. These encouraging findings emphasize the need for further experimental investigations to validate the performance of corrugated polymer-based heat exchangers in low-temperature applications.

Simulation is a proven technique that uses computational, mathematical, and machine learning models to represent the physical characteristics, expected or actual operation, and control strategies of a building and its energy systems. Simulations can be used in a number of tasks along the deep renovation life cycle, including: (a) integrating simulations with other knowledge-based systems to support decision-making, (b) using simulations to evaluate and compare design scenarios, (c) integrating simulations with real-time monitoring and diagnostic systems for building energy management and control, (d) integrating multiple simulation applications, and (e) using virtual reality (VR) to enable digital building design and operation experiences. While building performance simulation is relatively well established, there are numerous challenges to applying it across the renovation life cycle, including data integration from fragmented building systems, and modelling human-building interactions, amongst others. This chapter defines the building performance simulation domain outlining significant use cases, widely used simulation tools, and the challenges for implementation.
