White noise limits for inertial particles in a random field

GA Pavliotis, AM Stuart - Multiscale Modeling & Simulation, 2003 - SIAM
In this paper we present a rigorous analysis of a scaling limit related to the motion of an
inertial particle in a Gaussian random field. The mathematical model comprises Stokes's law …

Anisotropic active Brownian particle with a fluctuating propulsion force

JL Thiffeault, J Guo - Physical Review E, 2022 - APS
The active Brownian particle (ABP) model describes a swimmer, synthetic or living, whose
direction of swimming is a Brownian motion. The swimming is due to a propulsion force, and …

Stochastic reductions for inertial fluid-structure interactions subject to thermal fluctuations

G Tabak, PJ Atzberger - SIAM Journal on Applied Mathematics, 2015 - SIAM
We investigate the dynamics of elastic microstructures within a fluid that are subjected to
thermal fluctuations. We perform analysis to obtain systematically simplified descriptions of …

Stochastic mode reduction for the immersed boundary method

AJ Majda, PR Kramer - SIAM Journal on Applied Mathematics, 2004 - SIAM
We apply the formulation of a stochastic mode reduction method developed in a recent
paper of Majda, Timofeyev, and Vanden-Eijnden [Comm. Pure Appl. Math., 54 (2001), pp …

On the stochastic immersed boundary method with an implicit interface formulation

Q Du, M Li - Discrete and Continuous Dynamical Systems-B, 2010 - aimsciences.org
In this paper, we present a consistent and rigorous derivation of some stochastic fluid-
structure interaction models based on an implicit interface formulation of the stochastic …

Incorporating thermal fluctuations into the immersed boundary method

PR Kramer, CS Peskin - Computational Fluid and Solid Mechanics 2003, 2003 - Elsevier
Publisher Summary This chapter presents a new computational method for simulating
microscopic processes in physiology, which accounts for stochastic thermal fluctuations and …

Analysis of a stochastic implicit interface model for an immersed elastic surface in a fluctuating fluid

Q Du, M Li - Archive for rational mechanics and analysis, 2011 - Springer
We present some mathematical analyses of a recently proposed stochastic implicit interface
model for an elastic surface immersed in an incompressible viscous fluid subject to …

[PDF][PDF] Systematic stochastic reduction of inertial fluid-structure interactions subject to thermal fluctuations

G Tabak, PJ Atzberger - arXiv preprint arXiv:1211.3798, 2013 - math.ucsb.edu
We present analysis for the reduction of an inertial description of fluid-structure interactions
subject to thermal fluctuations. We show how the viscous coupling between the immersed …
