Computational fluid dynamics applied to gas-liquid contactors. [PDF]
, 1997 In this paper a `hierarchy of models¿ is discussed to study the fluid dynamic behaviour of gas-liquid bubble columns. This `hierarchy of models¿ consists of a Eulerian-Eulerian two fluid model, a Eulerian-Lagrangian discrete bubble model and a Volume ...

Smoothed particle hydrodynamics - A new approach for modeling flow in oscillatory baffled reactors
Computers and Chemical Engineering, 2019 Existing numerical models of mixing processes in oscillatory baffled reactors (OBR) are mainly Eulerian-based. An alternative Lagrangian based methodology, Smoothed-Particle Hydrodynamics (SPH), for predicting flow patterns and assessing mixing ...

Traveling and pinned fronts in bistable reaction-diffusion systems on network [PDF]
, 2012 Traveling fronts and stationary localized patterns in bistable reaction-diffusion systems have been broadly studied for classical continuous media and regular lattices. Analogs of such non-equilibrium patterns are also possible in networks.

Influence of Mixing Intensity on Lysozyme Crystallization in a Meso Oscillatory Flow Reactor [PDF]
Crystal Growth & Design, 2018 The influence of mixing intensity on protein crystallization has been investigated for the first time in a meso oscillatory flow reactor (meso-OFR). For this, lysozyme crystallization was studied in batch at different oscillation amplitudes and frequencies.

Selection Strategies for Flexible Pressure Sensor Electrode Materials Toward Ultrafast Response
Advanced Functional Materials, EarlyView.This study reveals, for the first time, how the electrode–organic interface governs the temporal performance of flexible pressure sensors. By pairing high‐conductivity CVD PEDOT with commonly used metal electrodes, the authors demonstrate that interfacial energy alignment dictates microsecond‐scale response, providing a straightforward design strategy ...
