Theoretical and experimental investigation on heating moving packed beds in a single tube with constant wall temperature

Yupu Yu et al.

Summary: A heat transfer model was proposed to describe the heat transfer behavior of moving packed beds, which was validated by experimental results showing its applicability over a wide range of particle flow rates. Increasing the particle flow rate was found to increase contact thermal resistance and reduce convective thermal resistance, leading to a decrease in heat transfer rates.

Predicting heat transfer coefficient of a shell-and-plate, moving packed-bed particle-to-sCO2 heat exchanger for concentrating solar power

Wenchao Fang et al.

Summary: The study evaluates the heat transfer characteristics of a shell-and-plate, moving packed-bed heat exchanger through numerical modeling, finding a universal correlation between the local heat transfer coefficient and particle flow properties. The heat exchanger exhibits a two-regime behavior: in the low particle flow rate regime, performance depends on particle flow velocity and channel width, while in the high flow rate regime, the effective conductivity of the particle flow is the determining factor.

Numerical investigation of heat resistances in uniform dense granular flows along a vertical plate

Zhigang Guo et al.

Summary: In this study, the heat transfer coefficients in ordered and random packing sphere particles were simulated using the finite volume method to investigate contact resistance and penetration resistance. It was found that contact resistance is mainly determined by the effective thermal conductivity in the wall region, while penetration resistance is affected by heat capacity, thermal conductivities, and particulate structures. The impact is reflected in the modified equivalent heat absorption coefficients in granular flows.

The cohesive behavior of granular solids at high temperature in solar energy storage

F. J. Duran-Olivencia et al.

Summary: This study investigates the impact of temperature and consolidation on granular flow through storage routes. The results show that as temperature and consolidation increase, the cohesion of powders intensifies, affecting flowability. To mitigate this issue, the study explores the use of nanosilica coatings on limestone particles to prevent cohesion enhancement at high temperatures.
