Route to chaos for combustion instability in ducted laminar premixed flames
TL;DR: It is shown that, as the location of the heat source is gradually varied, self-excited periodic thermoacoustic oscillations undergo transition to chaos via the Ruelle-Takens scenario.
Journal ArticleDOI
Bifurcations of Self-Excited Ducted Laminar Premixed Flames
TL;DR: In this article, a simple setup consisting of ducted laminar premixed conical flames was used to investigate the features of nonlinear thermoacoustic oscillations, and it was observed that the system undergoes a series of bifurcations leading to characteristically different nonlinear oscillations.
Journal ArticleDOI
Bifurcation analysis of thermoacoustic instability in a horizontal Rijke tube
TL;DR: In this article, a bifurcation analysis of the dynamical behavior of a horizontal Rijke tube model is performed, including the amplitude of the unstable limit cycles, and the linear and nonlinear stability boundaries are obtained for the simultaneous variation of two parameters of the system.
Journal ArticleDOI
Averaging Oscillations with Small Fractional Damping and Delayed Terms
Pankaj Wahi,Anindya Chatterjee +1 more
TL;DR: In this article, the authors demonstrate the method of averaging for conservative oscillators which may be strongly nonlinear, under small perturbations including delayed and/or fractional derivative terms.
Journal ArticleDOI
Self-interrupted regenerative metal cutting in turning
Pankaj Wahi,Anindya Chatterjee +1 more
TL;DR: In this paper, a new approach is used to study the global dynamics of regenerative metal cutting in turning, where the cut surface is modeled using a partial differential equation coupled, via boundary conditions, to an ordinary differential equation (ODE) modeling the dynamics of the cutting tool.
