Special Issue Information

Dear Colleagues,

In recent years, the demand for energy-efficient and sustainable technologies has proliferated to reduce carbon emissions and protect the environment in applications such as industry, agriculture, commerce, transportation, food industry, and healthcare. In this context, heat exchangers are essential in various industrial processes as well as in heating, ventilation, air conditioning, and refrigeration systems. The development of efficient, cost-effective, and environmentally friendly heat exchange technologies is imperative.

This Special Issue aims to comprehensively overview the latest heat exchangers for sustainable technology applications. This Special Issue focuses on new and innovative technologies that improve the performance of heat exchangers while reducing their environmental impact.

The scope of this Special Issue includes, but is not limited to, the following topics:

  • Heat exchanger applications in energy recovery, heat recovery, solar thermal systems, geothermal systems, renewable energy systems, energy-efficient buildings, and low-carbon transportation applications.
  • Thermal management in sustainable technologies.
  • Advances in heat pipes applications.
  • Heat exchanger design with phase change materials and various tube inserts.
  • Micro/nano-scale, compact, and integrated heat exchangers.
  • Nano/micro heat sink designs for the thermal management of high-heat-flux surfaces.
  • Advanced heat carrier fluids, including nanomaterials and phase change materials.
  • Advanced numerical simulation, experimental methods, and artificial intelligence (AI) to optimize and evaluate heat exchanger performance.
  • Life-cycle assessment of heat exchangers.
  • Techno-economic analysis of heat exchanger systems.
  • Case studies and real applications of heat exchangers in sustainable technologies.
  • Energetic and exergetic analyses of heat exchangers.

Prospective authors are invited to submit original research articles, review articles, and case studies that address the above topics of interest. All submitted manuscripts will undergo a rigorous peer-review process, and the best contributions will be selected for publication in this Special Issue. This Special Issue will be of interest for researchers, engineers, and practitioners in energy, thermal science, sustainability, and environmental engineering; policymakers; and stakeholders involved in promoting and implementing sustainable technologies.

We look forward to receiving your contributions and making this Special Issue a great success.

Lattice structures such as triply periodic minimal surface (TPMS) structures have gained significance due to advancements in additive manufacturing, particularly 3D printing, which enable their engineering to be tailored to specific applications, such as heat exchangers. While traditional heat exchanger designs have been extensively studied, investigations into the thermal performance of TPMS structures are limited. Considering the extensive range of the geometric design variations in TPMS structures, highly efficient structures on par with the performance of conventional heat exchanger designs can be expected. This study aims to comprehensively evaluate the thermal and flow characteristics of a specific TPMS structure (Fischer Koch S), and, in particular, the impact of various volume fractions on its heat transfer performance and on its friction factor. Another key objective of this study is to develop Nusselt and friction factor correlations as a function of the investigated volume fractions for potential use in future design tools. To this end, a broad CFD study was carried out. Additionally, this study provides insights into the procedures involved in generating Fischer Koch S geometries and the modeling methodology employed in CFD investigations. Based on the results of the CFD study, the thermal and fluid dynamic performances of Fischer Koch unit cells were evaluated, resulting in heat transfer coefficients up to 160 W/m2K for the investigated structures. A comparison between the heat transfer coefficient of the examined TPMS structure and a conventional plate heat exchanger suggested a potential increase in the heat transfer coefficient of approximately 35%. The generated CFD data were subsequently utilized to formulate fitting correlations for the Nusselt number and friction factors as a function of the volume fraction. The fitted parameters of these correlations are provided in this work. Full article

A ground-source heat pump (GSHP) system is a renewable energy technology that effectively reduces greenhouse gas emissions and consequently mitigates the progression of global warming. The thermal efficiency of ground heat exchangers (GHEs) is a critical component in the GSHP system that must be accurately estimated for its long-term operationality. Therefore, in this study, the thermal performance of double-spiral GHEs incorporated within the thermal piles of a zero-energy building in Sapporo, Japan, was investigated using the actual measured data obtained from the site and a novel metric, namely, the coefficient of heat extraction/injection, for a more precise evaluation. Moreover, this study assessed the coefficient of performance (COP) of the GSHP units during various periods of cooling or heating. The temperature of the circulating fluid remained within an ideal operational range over an operational period of 2 years, and the COP calculations indicated a high operational efficiency. The results derived in this study substantially exceeded those of traditional U-tube GHEs, indicating the enhanced efficiency and superior performance of large-diameter thermal piles with augmented thermal capacity. Our findings suggest that GSHP systems with double-spiral-tube GHEs have superior efficiency than conventional GHEs. Full article
