Laboratory investigations of a chaotic flow using braid theory
Describing transport in fluid flows has been a long-standing challenge in dynamical systems theory, with applications to industrial and natural flows. The detection of Lagrangian structures that stay coherent over time helps gain insight into the evolution of a system's dynamics and the fate of …

State Feedback Control of a Single-Loop Thermosyphon System Via a Quotient Controller
… to design a quotient controller to stabilize a chaotic flow in a single loop thermosyphon system with a high heat index. The thermosyphon loop is heated from below and cooled from above, which causes time-dependent chaotic flow when the external heat index is above a threshold value. Our goal …

The rotor-oscillator flow : searching for coherence amidst chaos
Chaotic mixing of highly viscous fluids is common in many biological and industrial processes. This study aims to gain insight about the properties of such common processes by examining one particular case of viscous, chaotic mixing: the rotor-oscillator flow. For some couplings of the rotor motion …

Flow Instabilities in Flute-like Instruments
… has been made to investigate more about the flow of air in flutes using 2D Direct Numerical Simulation. An analysis of the response of the jet of air by varying the jet width, profile, offset, and Reynolds number, and the flute labium angle in a 2D domain is the main focus of this study. We …

Development of Micro to Milli-Scale Multiphase Reactors with and Without Solids for Integration Into Mini-Monoplants
… the first, the impact of fluids (CO₂(g), water) flow rates, channel geometry, and presence of surfactant (ethanol) on the resulting gas-liquid flow regime (bubble, bubble/slug, annular), pressure drop and interphase mass transfer coefficient (𝑘𝑙𝑎) are investigated. Here, the interphase mass …

Neural networks for the prediction of chaos and turbulence
… in multiple engineering applications. Predicting chaotic dynamics is challenging because infinitesimal perturbations to the system’s initial conditions grow exponentially in time. To further add complexity to the phenomenon, chaotic systems may come in different forms, such as extreme and …
