A linear model for control of thermoacoustic instabilities on annular domain
42nd IEEE International Conference on Decision and Control (IEEE Cat. No.03CH37475), 2004We present a distributed linear model of thermoacoustic instability in form of a set of coupled PDEs including an acoustic model based on potential Euler formulation, a fully distributed fuel transport model based on advection equation, and a fuel-sensitive heat release model based on assumption of fixed flame location.

Multiparameter Elliptic Equations in Annular Domains
2005Using fixed point theorems of cone expansion/compression type, the upper-lower solutions method and degree arguments, we study existence, non-existence and multiplicity of positive solutions for a class of second-order ordinary differential equations with multiparameters.

Collective behavior of fish shoals in one-dimensional annular domains
Proceedings of the 2010 American Control Conference, 2010In this work, we study the collective behavior of fish shoals in annular domains. Shoal mates are modeled as self-propelled particles moving on a discrete lattice. Collective decision making is determined by information exchange among neighbors. Topological distances are used to specify neighborhoods within the fish shoal. We employ random variables to

A regularization method for a Cauchy problem of Laplace's equation in an annular domain
Mathematics and Computers in Simulation, 2012The Cauchy problem \[ \Delta u=0\quad \text{in} \quad S, \] \[ u= f \quad on \quad \Gamma,\quad \frac{du}{d\nu}= g \quad \text{on} \quad\Gamma, \] is defined in an annular domain \( S\subset \mathbb R^{2}\) with the boundary \( dS=\Gamma\;U \gamma \), where \( \Gamma\) and \(\gamma\) are two circles of radius \( r_{1}>r_{2}\). The functions \(f\) and \(

Time Domain Simulation of Combustion Instabilities in Annular Combustors
Volume 1: Turbo Expo 2002, 2002A novel method for the simulation of combustion instabilities in annular combustors is presented. It is based on the idea to solve the equations governing the acoustics in the time domain and couple them to a model for the heat release in the flames. The linear wave equation describing the temporal and spatial evolution of the pressure fluctuations is ...

Thermal Stresses in Anisotropic and Radially Inhomogeneous Annular Domains
Journal of Thermal Stresses, 2008This paper presents an analytical approach for construction of solutions to the plane quasi-static, non-axially-symmetric elasticity and thermoelasticity problems for cylindrically anisotropic and radially inhomogeneous hollow cylinders and disks subjected to in-plane external force loadings and temperature distribution. This approach is based upon the
