Summary: This review provides an in-depth analysis of the preparation, stability, and thermophysical properties of graphene nanoplatelets (GNP) nanofluids, and explores their applications in heat exchangers, solar thermal collectors, and heat pipes. The study finds that covalently functionalised GNP nanofluids outperform non-covalently functionalised in terms of stability and heat transfer coefficients. As particle size decreases, stability and heat transfer performance improve, while thermal conductivity and convection coefficients increase with nanofluid concentration and temperature.

Summary: This study numerically investigated the performance of a small-sized plate heat exchanger with chevron type corrugation pattern and validated the results with experimental tests. The influence of flow regime and geometrical parameters such as chevron angle, corrugation depth, and corrugation pitch on the performance of the heat exchanger were evaluated. It was found that the angle of 60 degrees and the ratio of corrugation depth to pitch had significant effects on the heat transfer and friction characteristics of the heat exchanger.

Summary: In the past decade, there has been a growing interest in studying energy systems for the combined management of power vectors. Most of the published works focus on finding the optimal design and operations of Multi Energy Systems (MES). However, for newcomers to this field, understanding how to achieve the desired optimization details while controlling computational expenses can be challenging and time-consuming. This paper presents a novel approach to analyzing the existing literature on MES, with the aim of guiding practical development of MES optimization. Through the discussion of six case studies, the authors provide a mathematical formulation as a reference for building the model and emphasize the impact of different aspects on the problem nature and solver selection. In addition, the paper also discusses the different approaches used in the literature for incorporating thermal networks and storage in the optimization of multi-energy systems.

Summary: This paper investigates the heat transfer mechanism and factors influencing thermal radiation in the process of supercritical water gasification (SCWG) of coal, and proposes a comprehensive numerical model to simulate the process. Experimental validation results show that thermal radiation accounts for a significant proportion of the total heat exchange in the reactor and a large amount of radiant energy exists in the important spectral range of supercritical water.
