Challenges and enablers in fluidization technology
AIChE Journal, EarlyView.Abstract Gas–solid fluidized beds provide excellent heat and mass transfer for high‐throughput operations from coating to catalytic conversion and underpin emerging low‐carbon technologies. Yet industrial reliability, scale‐up, and control lag scientific understanding, particularly as finer, stickier, and more variable feedstocks increasingly challenge

AIChE Journal, EarlyView.Abstract Mixed‐conducting ceramic hollow fiber membranes are a versatile platform for oxygen separation, value‐added chemical production, and oxy‐combustion. Because oxygen permeation is thermally activated, these systems typically rely on bulky, energy‐intensive furnaces that suffer from low efficiency and large thermal inertia.

On the mechanics of the grinding process – Part I. Stochastic nature of the grinding process
International Journal of Machine Tools and Manufacture, 2003Abstract Grinding of metals is a complex material removal operation involving cutting, ploughing, and rubbing depending on the extent of interaction between the abrasive grains and the workmaterial under the conditions of grinding. It is also a stochastic process in that a large number of abrasive grains of unknown geometry, whose geometry varies ...

Process Monitoring in Grinding
CIRP Annals - Manufacturing Technology, 2002Abstract The grinding process is characterised by a high number of cutting edges undergoing non-uniform wear, this also typifies a highly non-stationary process. Pure process modelling in order to understand the grinding mechanisms and to predict the work result is difficult.

Development of the process model for plunge grinding and optimization of grinding process
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2011This article presents improved grinding roughness model established for cylindrical plunge grinding though analysing the existing roughness models. The proposed roughness model is to consider the uncertain effects of grinding, such as changes of grinding conditions and circumstance, as grinding procedure is progressed.

Monitoring and Diagnosis of a Grinding Process
IFAC Proceedings Volumes, 1991Abstract A rational and reliable (i.e. experimentally grounded) approach to the advanced monitoring and diagnostics of coal pulverizers is presented in this paper. Two different forms of the dynamic model of the grinding process are proposed: a simulation model, exactly accounting for the distributed nature of the grinding process and for the various

Modelling and optimization of grinding processes
Journal of Intelligent Manufacturing, 1998The paper describes different methods for modelling and optimization of grinding processes. First the process and product quality characterizing quantities have to be measured. Afterwards different model types, e.g. physical–empirical basic grinding models as well as empirical process models based on neural networks, fuzzy set theory and standard ...

Modeling and Predicting Grinding Force of the Grinding Process
Advanced Materials Research, 2014A new method for predicting the grinding force is developed in this paper. The grinding forces model is build by divided it into cutting deformation force and sliding force and combine the undeformed chip thickness which assume the height of grits obey the Rayleigh distribution.

Grinding wheel effect in the grind-hardening process
The International Journal of Advanced Manufacturing Technology, 2007The grind-hardening process is based on the utilization of the generated heat in the grinding zone for inducing a metallurgical transformation on the surface of the ground workpiece. The workpiece surface is locally heated above the austenitization temperature and subsequently is quenched to increase surface hardness. A theoretical model was developed
