Summary: Reverse electrodialysis (RED) is investigated for energy conversion performance of sodium salt solutions with different ion valence ratios in symmetric and asymmetric pH configurations. Increasing pH weakens performance for 1:1 and 1:3 salts in symmetric pH configuration, while for 1:2 salt, the power density and energy conversion efficiency initially increase and then decrease. In asymmetric pH configuration, increasing pH of low concentration solution reduces power density and energy conversion efficiency, while increasing pH of high concentration solution decreases and then increases power and efficiency for 1:1 salt, increases and then decreases for 1:2 salt, and decreases overall for 1:3 salt due to OH- effects.

A two-phase pump-assisted loop heat pipe with two evaporators in parallel was manufactured to enhance heat transfer performance, increase transport distance, and accommodate multiple heat sources. Tests showed smooth operation with minimal interaction between the two evaporators, with evaporator 2 outperforming evaporator 1 due to a higher porosity resulting in more sufficient evaporation liquid. Increasing heat load and heat sink temperature reduced the evaporator thermal resistance.

Summary: This study designs and investigates the flow and heat transfer performance of two-phase minichannel cold plates with a 10 kW heat load. Numerical simulation is used to guide the optimization of the structure at both the channel and whole levels, which is in line with the experimental results. An abnormal phenomenon of temperature increase with flow rate is observed and explained by a change in boiling point. The impact of channel structure, fluid characteristics, flow uniformity, and pressure resistance on cold plate temperature and pressure drop are explored. The fusiform channel outperforms the rectangular channel and refrigerant R1234ze(E) performs better than R1233zd(E) in the cold plate. Methods for improving flow uniformity and pressure drop are explained and tested. The study provides a reference for designing high-power two-phase cold plates.

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.
