Hydrodynamics of spout-fluid beds [PDF]

Powder Technology, 1985
Abstract Experiments were carried out in a half-column incorporating auxiliary flow, introduced through up to five slots along a 60° conical base, in addition to a central flow of air. The column had a diameter of 0.15 m and inlet diameters of either 19 or 25 mm. Three different types of particle were investigated, all with mean particle sizes in the

Mathematical Modeling and Pointwise Validation of a Spouted Bed Using an Enhanced Bed Elasticity Approach

Energies, 2020
With a Euler–Euler (E2P) approach, a mathematical model for predicting the pointwise hydrodynamic behavior of a spouted bed was implemented though computational fluid dynamics (CFD) techniques.

Spectral analysis: A Contribution to Control Strategy in Spouted Bed

Chemical Engineering Transactions, 2013
The stability of fluid dynamics regime is one of the most desired objectives to ensure the good performance of processes in spouted bed equipment. However, the major problem in these processes is the lack of a control variable with fast response and easy

Comparison of modelling approaches for liquid fluidized beds

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study presents a comparison of three promising numerical models for the detailed simulation of liquid–solid fluidized bed. These models differ in their treatment of the solid phase, ranging from treating each particle individually to treating the collection of particles as a continuum.

A novel bubbling fluid bed reactor for the autothermal pyrolysis of waste plastics

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract A new pilot‐scale fluidized bed reactor operated under continuous conditions was developed and tested for the thermal pyrolysis of high‐density polyethylene (HDPE). The study focused on assessing the reliability and operability of the system under different operating conditions (400–550°C), while monitoring mass and energy balances, product ...

Between the Indian Ocean and the Gulf: Ceramics From Ḥattā Oasis in the Emirate of Dubai

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT This study presents the ceramic finds from archaeological investigations conducted in 2024 at two settlements: ‘Islamic Village' and Suhaila 2, one of a number of mountain villages of the Late Islamic period within the Ḥattā Oasis: a high‐altitude exclave in the Emirate of Dubai. The sites are located on the northeastern slopes of Jabal Qallāt

Responding Ethically to Violence From Patients and Families in the Hospital Emergency Department: A Symbiotic Empirical Ethics Study

Bioethics, EarlyView.
ABSTRACT Violent behaviour by patients and families is a significant issue facing healthcare providers, with a particularly high prevalence in hospital emergency departments. Occupational violence and aggression (OVA) puts both staff and patients at risk of physical and psychological harm and can affect the delivery of timely patient care.

Examining parent emotion socialization with children in daily life

Family Relations, EarlyView.
Abstract Objective We conducted a multilevel exploratory factor analysis of the Parent Emotion Socialization in Daily Life (PEDL) questionnaire to examine the within‐ and between‐person factor structure of emotion socialization (ES) practices. Further, we assessed how identified factors related to child social–emotional outcomes.

A Preliminary Research on a Plasma Spout-Fluid Bed Reactor

Energy and Power Engineering, 2013
A laboratory-scale plasma spout-fluid bed reactor with a 10 kW DC plasma torch was developed and tested using quartz sand particle and rice hull. The preliminary experimental results including particle recirculation and attrition, bed temperature distribution and stability, as well as biomass gasification system energy balance were presented in this ...

“They need to get a new program”: Experiential frictions with the gender of care in the 12 step program for ethnically Mexican women

Medical Anthropology Quarterly, EarlyView.
Abstract Using gender as an analytic, I parse out how the historical gendered, classed, and racialized roots of the 12 Step Program remain present in its therapeutic model, even in global contexts beyond its original formulation. These foundations continue to shape therapeutic logics and experience within the Program, in positive and negative ways.
