On 4th July, Kai-en YANG (D3), Sakai lab, Department of Nuclear Engineering and Management, recieved Best Poster Award at The 10th International Conference on Discrete Element Methods (DEM10) .
Best Poster Award
It was awarded to the outstanding poster presentations in DEM10.
Explanation about the award
Title: High-speed Simulations using Multi-timescale Reduced-Order Model in Gas-Solid Flows of a Large-scale Fluidized Bed
In this study, a multi-timescale reduced order model (MT-ROM) is validated in the gas-solid flows of a large-scale fluidized bed for high-speed simulations. This model uses a posteriori error estimate to avail the advantages of the data-driven and can decide the optimal training data for data-driven ROM without the physical and temporal constraints. As a result, the MT-ROM was validated in a large-scale fluidized bed for its effectiveness, the acceleration is up to 1900 times comparing to the conventional DEM-CFD method with relative errors maintained under 5%. Moreover, the real-time simulations of bubbling behavior and pressure drop of the fluidized bed were achieved by coupling MT-ROM with GPU computations and LSTM neural network.
Your impression & future plan
It is truly my honor to be awarded the Best Poster Award in DEM10, where the most outstanding researchers and studies on DEM were gathered. I’d like to express my highest gratitude to all the Sakai Lab members, especially Prof. Sakai and Asst Prof. Shuo Li. Their continued support and advice were indispensable for me to achieve this outstanding outcome.
