Bed voidage correlation in fluidized bed biofilm reactor
, 2000 A simple predictive correlation for bed voidage in a three-phase fluidized bed biofilm reactor (FBBR) has been proposed in this study, based on a relationship between the effective up-flow superficial liquid velocity (U-L) and the corresponding up-few ...

Energy Science &Engineering, Volume 13, Issue 7, Page 3503-3514, July 2025.ABSTRACT To address the challenges of poor performance and optimization in ultrahigh water cut oil fields, a comprehensive set of integrated simulation technologies tailored for these conditions was developed. The application of these technologies in multiple ultrahigh water cut oil fields was focused on the unique development characteristics of these ...

Radial voidage variation in randomly-packed beds of spheres of different sizes
, 1966 The packing arrangement of the particles in a tablet die, before pressing, has no hitherto been considered as a variable in the tabletting process. Because of the complexity of this subject, the present investigation has been restricted to monosized and ...

Predicting bed voidage in solid-liquid fluidization.
JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 1990 Previously published solid-liquid fluidization data and new experimental data were correlated to develop an explicit expression for bed voidage, e, in solid–liquid systems. Based on the observed deviation between the voidage predicted by the Richardson–Zaki18) equation (eRZ) and the actual voidage, this new correlation assumes the forme = ePK + (1 ...

An experimental research on ultrasonic parameters of coal
Gong-kuang zidonghua, 2018 Ultrasonic velocity, attenuation coefficient, time domain and frequency domain features in anthracite coal of Daanshan and fat coal of Sanhejian were studied by acoustic emission experimental techniques. Research results indicate that affected by voidage

Mathematical Modelling of Pyrolysis of Hardwood (Acacia)
Acta Technologica Agriculturae, 2020 This paper emphasises the analogous modelling of hardwood (acacia) pyrolysis. The impacts of physical characteristics of hardwood chips on the pyrolysis are examined through the conservation of biomass solid mass fraction.

RAPID ESTIMATION OF EFFECTIVE BED VOIDAGE FOR KIESELGUHRS [PDF]
Journal of the Institute of Brewing, 1993 Effective bed voidage is the most important characteristic of a filter aid enabling its selection and controlled usage. A rapid method for measurement for effective bed voidage has been developed, applicable only to kieselguhrs (diatomaceous earths), which relies on particle size analysis alone.
