Summary: This study investigates the performance of heat transfer and thermal energy storage medium in directly irradiated solid particle solar receivers (SPSRs). A novel concept of multi-component mixed particle systems with different mass ratios is proposed. The results show that the absorption performance of the particle systems increases with the addition of dark colored materials, but this effect becomes less obvious with the amount of additives. A quartz sand-silicon carbide particle system with a mass ratio of 7:3 may be the optimal choice for achieving both high receiver outlet temperature and low mass flow rate.

Summary: Limited space in electric vehicles (EVs) calls for a more compact and lightweight battery thermal management system (BTMS) to ensure lithium-ion battery safety. This study constructs PCM-based internal and external cooling models for cylindrical lithium-ion batteries, and verifies the effectiveness of the cooling design and numerical model. Different cooling modes, PCM melting point, PCM mandrel size, and thermal conductivity anisotropy are systematically evaluated for their effects on cooling performance. The results show that the internal cooling method performs optimally, with a maximum temperature difference of only 1.77 K compared to 6.77 K in external mode. Moreover, a PCM-based internal cooling mode with bidirectional heat transfer reduces heat transfer resistance, lowers temperature gradient, and achieves more even temperature distribution. Increasing the mandrel diameter of PCM from 2 to 5 mm decreases the battery's maximum temperature from 316.65 K to 314.10 K, and reduces the maximum temperature difference from 2.23 K to 1.32 K. The radial thermal conductivity significantly influences the internal heat transfer process of lithium-ion batteries and determines temperature difference uniformity. Minimizing battery size in the stratiform direction while ensuring energy density improves temperature uniformity.

Results show that steam increases averaged Nu by 16.59%-25.69% compared to air. Steam cooling of the rhombus-patterned ribbed surface demonstrates excellent cooling performance and overall thermal performance can be enhanced by decreasing rib height.

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.
