Rockslide and Impulse Wave Modelling in the Vajont Reservoir by DEM-CFD Analyses
Rock Mechanics and Rock Engineering, 2016 This paper investigates the generation of hydrodynamic water waves due to rockslides plunging into a water reservoir. Quasi-3D DEM analyses in plane strain by a coupled DEM-CFD code are adopted to simulate the rockslide from its onset to the impact with ...

AIChE Journal, EarlyView.Abstract In this work, an investigation of the transition from fixed to fluidized state of initially homogeneous binary‐solid mixtures due to an upward liquid flux was carried out. Like for analogous gas systems, it was confirmed that the full transition occurs over a range of fluid velocities, from the initial to the final fluidization velocity. Based

AIChE Journal, EarlyView.Abstract The effect of shear stress on cell behaviors should be considered for designing the suspension culture of mammalian cells. Computational flow dynamics (CFD) is a promising tool for estimating shear stress on cells, but the accuracy is limited due to resolution limitations.

Dynamic site‐interconversion reduces the induction period of methanol‐to‐olefin conversion
AIChE Journal, EarlyView.Abstract Reaction–diffusion coupling across the catalyst pore, grain, pellet, and reactor bed has been studied using a particle‐resolved transient microkinetic model applied to temperature‐programmed desorption and step‐response studies of methanol and dimethyl ether conversion over ZSM‐5 catalysts, respectively.

PairTilt: Design and Control of an Active Tilt‐Rotor Quadcopter for Improved Efficiency and Agility
Advanced Intelligent Systems, EarlyView.PairTilt is an actuated tilt‐rotor unmanned aerial vehicle capable of active shape reconfiguration, balancing simplicity, efficiency, and agility. Its H‐shaped frame incorporates pairwise tiltable rotors, which reduce gyroscopic torque and decouple key dynamics, enhancing maneuverability and reducing drag.

Computationally Efficient CFD Prediction of Bubbly Flow using Physics-Guided Deep Learning [PDF]
arXiv, 2019 To realize efficient computational fluid dynamics (CFD) prediction of two-phase flow, a multi-scale framework was proposed in this paper by applying a physics-guided data-driven approach. Instrumental to this framework, Feature Similarity Measurement (FSM) technique was developed for error estimation in two-phase flow simulation using coarse-mesh CFD ...
