Exponential rate of convergence to equilibrium for a model describing fiber lay-down processes
نویسندگان
چکیده
This paper is devoted to the adaptation of the method developed in Dolbeault et al. [2011, 2009] to a Fokker-Planck equation for fiber lay-down which has been studied in Bonilla et al. [2007/08], Götz et al. [2007]. Exponential convergence towards a unique stationary state is proved in a norm which is equivalent to a weighted L norm. The method is based on a micro / macro decomposition which is well adapted to the diffusion limit regime.

Exponential Decay to Equilibrium for a Fiber Lay-Down Process on a Moving Conveyor Belt
We show existence and uniqueness of a stationary state for a kinetic Fokker-Planck equation modeling the fibre lay-down process in the production of non-woven textiles. Following a micromacro decomposition, we use hypocoercivity techniques to show exponential convergence to equilibrium with an explicit rate assuming the conveyor belt moves slow enough. This work is an extention of [2], where th...
متن کاملOptimum Pressure Distribution in Design of Cryogenic NGL Recovery Processes
A type of novel hypercross-linked fiber adsorbent was obtained by sulfonation and cross-linking reaction of polypropylene fiber grafted styrene-divinylbenzene. The aim of the fiber sulfonation and cross-linking method was to prepare rigid three dimensional networks in the entire fiber and change the ion exchange capacity of fiber. The hypercross-linked fiber adsorbent possesses a principall...
متن کاملAsymptotic behavior of a system of two difference equations of exponential form
In this paper, we study the boundedness and persistence of the solutions, the global stability of the unique positive equilibrium point and the rate of convergence of a solution that converges to the equilibrium $E=(bar{x}, bar{y})$ of the system of two difference equations of exponential form: begin{equation*} x_{n+1}=dfrac{a+e^{-(bx_n+cy_n)}}{d+bx_n+cy_n}, y_{n+1}=dfrac{a+e^{-(by_n+cx_n)}}{d+...
متن کاملHydrodynamic Limit of a Fokker--Planck Equation Describing Fiber Lay-Down Processes
In this paper, a stochastic model [5] for the turbulent fiber laydown in the industrial production of nonwoven materials is extended by including a moving conveyor belt. In the hydrodynamic limit corresponding to large noise values, the transient and stationary joint probability distributions are determined using the method of multiple scales and the Chapman-Enskog method. Moreover, exponential...
متن کاملEstimation of the Domain of Attraction of Free Tumor Equilibrium Point for Perturbed Tumor Immunotherapy Model
In this paper, we are going to estimate the domain of attraction of tumor-free equilibrium points in a perturbed cancer tumor model describing the tumor-immune system competition dynamics. The proposed method is based on an optimization problem solution for a chosen Lyapunov function that can be casted in terms of Linear Matrix Inequalities constraint and Taylor expansion of nonlinear terms. We...
