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

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

The Canadian Journal of Chemical Engineering, EarlyView.Spouted bed drying of mango peels with colloidal SiO2 and corn starch produces a free‐flowing powder with reduced agglomeration, increased drying yield, and preserved antioxidant and polyphenol content. Abstract The production of polyphenol‐rich powders is a promising strategy for valorizing agro‐industrial byproducts. This study evaluated drying yield,

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 ...

The Gender of Fossil Fuels: Oil and Domestic Perils in Mandate Palestine
Gender &History, EarlyView.ABSTRACT This article explores the gender dynamics behind the rise of kerosene – an oil derivative – as the main domestic fuel in Mandate Palestine. It argues that these dynamics were constitutive in determining who began to use oil, where and for what purposes, in turn demonstrating that women in Palestine were the promoters and targets of a campaign ...

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 ...

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
