Study of Thermoacoustic Phenomenon in a Rijke Tube

open access: yesProcedia Engineering, 2014
AbstractThermoacoustics is concerned with the interactions between heat (thermo) and pressure oscillations in gases (acoustics). A “Rijke Tube”, named after its inventor, is a fundamental tool for studying thermoacoustic phenomenon. Rijke's tube turns heat into sound, by creating a self-amplifying standing wave.

Rijke tube: A nonlinear oscillator

open access: yesChaos: An Interdisciplinary Journal of Nonlinear Science, 2022
Dynamical systems theory has emerged as an interdisciplinary area of research to characterize the complex dynamical transitions in real-world systems. Various nonlinear dynamical phenomena and bifurcations have been discovered over the decades using different reduced-order models of oscillators.

Transfer learning of deep neural networks for predicting thermoacoustic instabilities in combustion systems

open access: yesEnergy and AI, 2021
The intermittent nature of operation and unpredictable availability of renewable sources of energy (e.g., wind and solar) would require the combustors in fossil-fuel power plants, sharing the same grid, to operate with large turn-down ratios. This brings

Feather function and the evolution of birds

open access: yesBiological Reviews, Volume 98, Issue 2, Page 540-566, April 2023., 2023
ABSTRACT The ability of feathers to perform many functions either simultaneously or at different times throughout the year or life of a bird is integral to the evolutionary history of birds. Many studies focus on single functions of feathers, but any given feather performs many functions over its lifetime. These functions necessarily interact with each

Predictive functional control for challenging dynamic processes using a simple prestabilization strategy

open access: yesAdvanced Control for Applications, Volume 4, Issue 2, June 2022., 2022
Abstract Predictive functional control (PFC) is a straightforward and cheap model‐based technique for systematic control of well‐damped open‐loop processes. Nevertheless, its oversimplified design characteristics are often the cause of diminished efficacy in more challenging applications; processes involving lightly damped and/or unstable dynamics have

Adaptive Backstepping Stabilization of Thermoacoustic Instability in a Linearized ODE-PDE Rijke Tube Model

open access: yesIEEE Access, 2023
This paper proposes an adaptive scheme for the boundary stabilization of thermoacoustic instability in the Rijke tube system using the backstepping method. The mathematical model of the system is characterized by a $2\times 2$ linear hyperbolic partial

A Microfluidics‐Based Screening Tool to Assess the Impact of Blood Plasma Factors on Microvascular Integrity

open access: yesAdvanced Biology, Volume 5, Issue 11, November 2021., 2021
Microvessels‐on‐chips are advanced in vitro models that are currently considered as future replacements of animal models. However, the high‐throughput use of microvessels‐on‐chips for patient‐on‐a‐chip studies is still lacking. This study develops an innovative method for screening plasma samples in the microvessel‐on‐a‐chip platforms that can be ...
