Summary: Phase-change materials (PCMs) have the potential to overcome the low energy density and utilization efficiency of solar energy. This study successfully improved the thermal conductivity of PCMs by adding high-pore-density copper metal foam (CMF) to paraffin wax. Experimental results showed that increasing the proportion of CMF can enhance heat transfer during the PCM melting process and improve the comprehensive heat transfer coefficient. When considering both heat storage capacity and heat storage rate, PCMs with a 0.86% CMF proportion exhibited the best heat storage performance.

Summary: The study investigated the thermal and thermoelectric performances of an integrated energy storage/release/harvesting system using PCM-based metal foam composite. Results showed that inserting metal foam in PCM improved heat dissipation and enhanced thermoelectric energy. Pure PCM provided the most thermoelectric energy during solidification due to highest latent heat release, but the composite with lower porosity had the best thermal control and highest thermoelectric energy harvest.

Summary: The paper proposes a method for intensifying the thermal response of phase-change materials (PCMs) in the shell-and-tube containment system by applying fin-assisted foam strips. It suggests using foam strips instead of full foam to achieve better enhancement rate in a more convection-friendly environment. Experimental results show that uneven fins with foam strips have the best enhancement potential compared to other additives in use, with melting rate enhancement up to 58 % and solidification rate enhancement up to 42 % depending on the type and volume fraction of the enhancement additive used.

Summary: The integration of phase change materials (PCMs) and metal foam has garnered significant attention. An adaptive metal foam arrangement strategy, with increasing porosity from inside to outside, has been proposed to address the non-uniformity issue. The simulation and experimental study on a vertical thermal energy storage (TES) tube showed that a smaller difference between the inside and outside subregions, along with a larger porosity difference, led to better thermal performance and faster phase change evolution. The optimal strategy (0.87-0.94-0.97) significantly shortened the melting duration and enhanced the efficiency of vertical metal foam TES systems.

Summary: The low thermal conductivity of phase change materials limits the heat transfer rate and application of latent heat storage systems. This numerical study examines the impact of two passive heat transfer enhancement techniques on the thermal performance of a latent heat storage system. The results show that the orientation and position of the heat transfer fluid tube have significant effects on the charging duration, while the discharging duration remains unchanged. The combined effect of orientation and eccentricity reduces the charging duration, but increases the discharging duration compared to the concentric domain.

By establishing NAPLs-contaminated soil models and using the Lattice Boltzmann Method (LBM) for calculation, an optimized three-dimensional model with high computational accuracy and efficiency is obtained. The study also finds that saturation and Nz parameters have a significant impact on calculation time, while the thermal conductivity of the two-dimensional model is more sensitive to anisotropy. The influence of porosity and NAPLs content on thermal conductivity should be considered during in-situ thermal desorption.

Summary: This study investigated the impact of upstream slot leakage on the endwall film cooling characteristics of turbine blades. Pressure Sensitive Paint (PSP) technology was used to measure the film cooling characteristics, and numerical analysis was conducted to evaluate the aerodynamic performance. It was found that increasing the mass flow ratio of the upstream slot enhanced film cooling, decreased aerodynamic losses, and reduced the strength of passage vortex. However, reducing the distance between the slot and the blade leading edge only enhanced film cooling without affecting the leakage coverage area.

Summary: We have developed an advanced experimental setup to investigate flow and heat transfer in an annular channel. The setup allows heat transfer measurements and flow visualization using a temperature-controlled inner tube. Measurements can be conducted in both single-phase and two-phase flow regimes. The setup ensures a uniform velocity field in the annular channel using specially designed inlet and outlet headers. The inner copper tube is heated by water and contains turbulators for enhanced heat transfer and thermocouples for temperature measurement. A three-dimensional conjugate heat transfer CFD model has been developed and validated to accurately estimate heat losses in the setup.
