Special Issue Information

Dear Colleagues,

This is the second edition of the previously successful Special Issue “Advances in Thermal Energy Storage and Applications”.

As an important type of technology for the construction and development of low-carbon, safe and efficient energy supply systems, thermal energy storage has broad application prospects in renewable energy utilization, power grid peak shaving and valley filling, industrial waste heat recovery, building energy conservation, thermal management for vehicles and power electronics, etc. Thermal energy storage could effectively solve the mismatch between the supply and demand of thermal energy with regard to time, space or intensity, as well as enhance system or device energy utilization. In recent years, thermal energy storage technologies, including sensible heat storage, latent heat storage, and thermochemical heat storage, have been deeply studied in different fields of heat utilization. With the enrichment of thermal storage scenarios and the improvement of the scale and quality of thermal storage, it is urgent and important to develop advanced thermal storage technologies that can realize efficient space–time transfer and utilization of thermal energy.

This Special Issue will present the latest research on new materials, systems, devices and methods for advanced thermal energy storage, as well as investigations into heat transfer, flow and physical and chemical mechanisms. Scholars are invited to submit original research, review, and perspective articles on the topics of interest for publication, which include, but are not limited to, the following:

  • Configuration design and optimization of high-efficiency thermal storage systems;
  • Preparation and optimization of materials with high thermal energy storage density;
  • Enhancement of the thermal and chemical stabilities of thermal storage material;
  • Thermodynamic and economic analyses of thermal storage systems;
  • Control of heat charging and discharging of thermal storage systems and devices;
  • Heat transfer control and enhancement of thermal storage devices;
  • Single-phase and multi-phase flow control of thermal storage devices;
  • Operation strategy optimization of thermal storage systems;
  • Smart fault detection and diagnosis of thermal storage systems;
  • Advanced simulation and testing approaches.

With the rapid advancement of integrated thermal management systems (ITMS) for new energy vehicles (NEVs), flow losses and hydrodynamic characteristics within multi-way valves have become critical determinants of system performance. In this study, a three-dimensional computational fluid dynamics model is established for a multi-way valve used in a representative NEV ITMS, where PAG46 coolant is employed as the working fluid. The steady-state pressure-loss characteristics under three typical operating modes—cooling, heating, and waste heat recovery—are investigated, together with the transient hydrodynamic response during mode switching. The steady-state results indicate that pressure losses are primarily concentrated in regions with abrupt changes in flow direction and sudden variations in cross-sectional area, and that the cooling mode generally exhibits the highest overall pressure loss due to the involvement of all flow channels and stronger flow curvature. Furthermore, a parametric analysis of the valve body corner chamfers and valve spool fillets reveals a non-monotonic dependence of pressure drop on chamfer radius, highlighting a trade-off between streamline smoothness and the effective flow cross-sectional area. Transient analysis, exemplified by the transition from heating to waste heat recovery mode, demonstrates that dynamic changes in channel opening induce a significant reconstruction of the internal velocity and pressure fields. Local high-velocity zones, transient pressure peaks, and pronounced fluctuations of hydraulic torque on the valve spool emerge during the switching process, imposing higher requirements on the torque output and motion stability of the actuator mechanism. Consequently, this study provides a theoretical basis and engineering guidance for the structural optimization and actuator matching of multi-way valves in NEV thermal management systems.
