Nanosilica to improve the flowability of fine limestone powders in thermochemical storage units
(Elsevier, 2021)
Fine powders are the cornerstone of new energy storage solutions to assist concentrated solar power plants. Though, their ability to behave like fluid can be seriously affected at high temperatures. This work investigates ...

The Sevilla Powder Tester: A Tool for Measuring the Flow Properties of Cohesive Powders at High Temperatures
(Hosokawa Powder Technology Foundation, 2022)
Understanding the flowability of cohesive powders at high temperature is of great importance for many industrial applications where these materials are handled at harsh thermal conditions. For instance, the Calcium-Looping ...

An automated apparatus for measuring the tensile strength and compressibility of fine cohesive powders
(American Institute of Physics, 2000)
This paper describes an apparatus based on a novel use of a powder bed, whereby the relationship between consolidation stress, tensile strength, and free volume of fine powder is measured. The powder to be tested is first ...

Flow Regimes in Fine Cohesive Powders
(American Physical Society, 1999)
Granular materials exhibit several regimes of behavior: plastic, inertial, fluidized, and entrained flow, but not all materials can pass through all of these states. Our concern is with the criteria that determine the ...

Efficacy of Nanosilica Coatings in Calcium Looping Reactors
(American Chemical Society, 2023)
Nanosilica coatings are considered a simple physical treatment to alleviate the effect of cohesion on powder flowability. In limestone powders, these coatings buffer the rise in cohesion at high temperatures. Here, we ...
