Wave focusing by submerged islands and gravitational analogues
Physical Review Research, 2022 We study water waves propagating over a smooth obstacle in a fluid of varying depth, motivated by the observation that submerged islands in the ocean act as effective lenses that increase the amplitude and destructive power of tsunami waves near focal ...

Fluid flow approximation of PEPA models [PDF]
Second International Conference on the Quantitative Evaluation of Systems (QEST'05), 2005 In this paper we present a novel performance analysis technique for large scale systems modelled in the stochastic process algebra PEPA. In contrast to the well-known approach of analysing via continuous time Markov chains, our underlying mathematical representation is a set of coupled ordinary differential equations (ODEs).

Bottom Multi-Parameter Bayesian Inversion Based on an Acoustic Backscattering Model
Journal of Marine Science and EngineeringThe geoacoustic and physical properties of the bottom, as well as spatial distribution, are crucial factors in analyzing the underwater acoustic field structure and establishing a geoacoustic model.

Blade coating analysis of a Williamson fluid
Results in Physics, 2017 In this article, a mathematical model of a blade coating analysis of the thin film of a Williamson fluid is developed when it passes through the small gap between a blade and a moving substrate.

Numerical approximation of fluid-structure interaction problems [PDF]
Applied and Computational Mechanics, 2008 This paper is devoted to numerical approximations of fluid-structure interaction problems. Namely the problem of interaction of turbulent flow over flexibly supported airfoil is addressed. In order to model the turbulence effects the flow is described by

An accurate fluid approximation for massive neutrinos in cosmology [PDF]
, 2023 A measurement of the neutrino mass scale will be achieved with cosmological probes in the upcoming decade. On one hand, the inclusion of massive neutrinos in the linear perturbation theory of cosmological structure formation is well understood and can be

Entropy approximations for simple fluids
Physical Review ELiquid state entropy formulas based on configurational probability distributions are examined for Lennard-Jones fluids across a range temperatures and densities. These formulas are based on expansions of the entropy in series of $n$-body distribution functions. We focus on two special cases.

A thin rivulet of perfectly wetting fluid subject to a longitudinal surface shear stress [PDF]
, 2008 The lubrication approximation is used to obtain a complete description of the steady unidirectional flow of a thin rivulet of perfectly wetting fluid on an inclined substrate subject to a prescribed uniform longitudinal surface shear stress.
