Journal ArticleDOI
Creeping flow relative to permeable spheres
TL;DR: In this paper, several possible solutions to the problem of creeping flow relative to an isolated permeable sphere are discussed and compared quantitatively, and the most satisfactory solutions are based upon Brinkman's extension of Darcy's Law.
Journal ArticleDOI
Drag coefficients of irregularly shaped particles
TL;DR: In this article, a new and accurate empirical correlation for the drag coefficient, C D, of variously shaped particles has been developed, based on the particle nominal diameter, Re, the ratio of the surface-equivalent-sphere to the nominal diameters, d A / d n, and the particle circularity, c.

Permeability of Fractal Aggregates
Xiao-yan Li,Bruce E. Logan +1 more
TL;DR: It is demonstrated through comparison with aggregate settling velocity data that the single-particle-fractal model does not provide realistic predictions of settling velocity as a function of aggregate size, and it is shown that the Carmen-Kozeny permeability equation does not produce realistic settling velocity relationships.

Ca-based synthetic materials with enhanced CO2 capture efficiency
TL;DR: In this paper, a critical review on the novel Ca-based sorbents developed in the last few years with improved thermal and mechanical stability is presented, which is mainly attributed to a decrease of the reactive surface area with the number of calcination/carbonation cycles.

Advantages to microbes of growth in permeable aggregates in marine systems1
Bruce E. Logan,James R. Hunt +1 more
TL;DR: In this article, the authors examined substrate removal by microorganisms in permeable aggregates with an analysis of mass transfer and found that the overall uptake by bacteria in aggregates can be up to 60% greater than uptake by dispcrscd bacteria.
