Summary: In this study, a radiative heat transfer model was developed and computational fluid dynamics were used to simulate concentrated solar energy absorption by a packed bed of silicon carbide. The effective conductivity for radiative heat transfer in the packed bed was modeled based on the study by Breitbach and Barthels, while the Zehner-Bauer-Schliinder conductivity model was used to calculate effective thermal conductivity. The two-dimensional numerical simulations with ANSYS Fluent 16.1 were in good agreement with literature data on temperature measurements of SiC particles in the packed bed.

Summary: This study revisits the classical problem of steady-state heat transfer from a single particle in a uniform laminar flow, assuming the thermal conductivity of the fluid changes linearly with temperature. Through a combination of asymptotic and scaling analyses, approximate expressions for the dimensionless heat transfer coefficient Nu of arbitrarily shaped particles are derived, covering the entire range of the Peclet number Pe. The results show that Nu can be decomposed into two parts under constant temperature boundary conditions, one related to Pe and the other mainly dependent on the proportionality constant of the conductivity-temperature relation; while under a uniform heat flux, Nu can be decomposed into a Pe-dependent part and a part solely varying with the proportionality constant.

Summary: This study analyzes the laminar flow through a semi-elliptic annulus formed between two confocal elliptical ducts driven by a constant pressure-gradient. Using the elliptic cylindrical coordinate system, exact solutions for wide and narrow semi-elliptic annuli are obtained. The velocity distribution, volume flow rate, shear stress, and Poiseuille number are expressed using non-dimensional physical parameters. The results show characteristic differences between wide and narrow semi-elliptic annuli. Additionally, a numerical method is formulated for obtaining the numerical solution, which agrees with the analytical results. Published under an exclusive license by AIP Publishing.

Summary: Latent heat thermal storage based on phase change material (PCM) in shell-and-tube heat exchangers can reduce power consumption of air conditioning systems. By optimizing the charging/discharging time of PCM and the operating conditions of the chiller, better performance can be achieved. Experimental validation shows that the optimal solution leads to a reduction in the inlet temperature by 1.25℃ and a maximum utilization of PCM by 40% of the initial amount. Further optimization results in a shell diameter reduction of 12 cm to exploit 72% of the PCM potential.

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.

Summary: This paper investigates the calculation method of thermal conductivity in NAPLs-contaminated soils. 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. This study demonstrates the importance of numerical simulations in improving the interpretation of complex experimental results.
