Summary: The study found that the microhole surface can achieve a superhydrophobic state, with the contact angle rapidly decreasing when the diameter is too large. As the microhole diameter increases, the relative radii of the x- and y-directions show an increasing trend, while an increasing spacing leads to a decreasing trend in the relative radii of x- and y-directions.

Summary: In this study, a lattice Boltzmann method is employed to simulate a particle-laden droplet under a simple shear flow. The effects of particle concentration, viscosity ratio of droplet to ambient fluid, and particle inertia on droplet deformation and particle movement are investigated. It is found that the addition of particles reduces the interfacial free energy and leads to increased droplet deformation. Additionally, the viscosity ratio and particle inertia both influence the droplet deformation, with the former showing a monotonic decrease and the latter having a significant effect only at high Reynolds numbers.

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. Enhancing radiative heat transfer can effectively increase the temperature of the reaction medium and the gasification rate.

Summary: Pulsating Heat Pipes (PHP) are passive two-phase heat transfer devices with a simple structure and high heat transfer capabilities. The actual unpredictability of their dynamic behavior during startup and thermal crisis hinders their large-scale application. An experimental apparatus is designed to investigate these phenomena systematically. The results show that increasing the number of evaporator sections and condenser temperature improves the performance of PHP. The condenser temperature also affects the initial liquid phase distribution and startup time.
