Time/Location: September 4th from 12:20-12:40pm at Research Showcase Session 3b
Abstract: Air classification of material has existed since ancient times. With the advancements in material science and innovative engineering technology, the demands for air-classification of sub-10 micron particles have increased exponentially in battery, 3D printing and food industries. However, the industry is investing resources to achieve the maximum efficiency of classification of ultra fine materials to minimise the carbon footprints.
Classification of materials using dynamic air classifier is one of the common methods widely used in the industry. Fan air flow, feed rate and rotor speed are main parameters to achieve optimised output for the classifier. Dynamic air classifier can also be altered via its structural parameters to achieve enhance the output. Particles below 10 microns being more receptive to smaller local vortexes, hence, depends more on the local structures of the classifier. Along with operational parameters, the design of air classifier rotor also plays a critical role in optimising its efficiency, especially in sub-10micron operational range. This research focuses on the enhancement of the rotor blade and rotor angle to investigate the dynamics of air and particles passing through the rotor. Lab-scale air classifier has been deployed to study the dynamics between rotor shape, air and particles. This research will explore the efficiency of air-classifier at different combinations of operational parameters, rotor shapes and particles.
Dr. Osamh S. Alshahed will present results from his research titled, Model Predictive Control Simulation of Pneumatic Conveying of Plastic Pellets Using Nonlinear Dynamics Analysis and Sparse Identification of Nonlinear Dynamics with Control.
Time/Location: September 4th from 12:20-12:40pm at Research Showcase Session 3a
Abstract: The study explores the integration of Model Predictive Control (MPC) and Sparse Identification of Nonlinear Dynamics with control (SINDYc) with nonlinear dynamics analysis to simulate the pneumatic conveying of plastic pellets. Nonlinear dynamics analysis measures were applied to data from a bottom arc-shaped electrostatic sensor of fully developed gas-solid flow in horizontal pipelines, including Lyapunov exponents, approximate entropy and recurrence rate. The study leverages SINDYc, a data-driven method, to identify sparse system models using the analysis measures. The MPC framework is then employed to optimise control inputs over a future horizon, ensuring desired nonlinear flow behaviour. The simulation framework assesses MPC’s performance, using three distinct SINDYc models for each analysis measure to understand their control system’s dynamics. Results showcase the ability to integrate MPC and SINDYc with the nonlinear dynamics analysis measures, highlighting improvements in system control.
The CHoPS conference presents a unique forum to promote the exchange of technical and scientific information across the academic and industrial sectors in the fields of solids flow, mechanical behavior of bulk materials, powder testing, segregation and mixing, modelling, etc. It is also intended to foster business and collaboration opportunities around the world. The scope of the conference is wide-ranging from pharmaceuticals to mining and minerals, food and chemicals and all other sectors that process powders and bulk solids. If you deal with particulates – you have to be at CHoPS! Few other conferences in the area are as large, as international, and as wide ranging in both industry and academic participation.
