Collision and Coagulation in the Infinite-Stokes-Number Regime [PDF]

open access: yesAerosol Science and Technology, 1998
This paper presents a theoretical description of collision and coagulation in the infinite-Stokes-number limit where particle motions are only weakly correlated with the fluid. A methodology for predicting the collision frequency and the particle mean energy is developed based on the assumption of a Maxwellian velocity distribution.

Low Mach number limit for the compressible Navier–Stokes equations with density-dependent viscosity and vorticity-slip boundary condition

open access: yesBoundary Value Problems, 2020
In this paper, we consider the three-dimensional compressible Navier–Stokes equations with density-dependent viscosity and vorticity-slip boundary condition in a bounded smooth domain.

Oseen's correction to stokes drag on axially symmetric arbitrary particle in transverse flow: A new approach [PDF]

open access: yesTheoretical and Applied Mechanics, 2014
In this paper, Oseen’s correction to Stokes drag experienced by axially symmetric particle placed in a uniform stream perpendicular to axis of symmetry(i.e. transverse flow) is obtained.

Efficiency of capture of inertia aerosol particles in a periodic cell with a porous cylinder

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2022
In this study, aerosol flow in circular and rectangular periodic cells of a regular row of porous cylinders is simulated. The hydrodynamic field of the carrier medium flow outside and in the domain of the porous cylinder is described in the approximation

About the use of the Stokes number for mathematical modeling of two-phase jet flows

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2019
The appropriateness of using the Stokes number as a single similitude parameter for representation of the results of research on two-phase jet flows in a criteria form was considered.

Kolmogorov's dissipation number and the number of degrees of freedom for the 3D Navier–Stokes equations [PDF]

open access: yesProceedings of the Royal Society of Edinburgh: Section A Mathematics, 2019
AbstractKolmogorov's theory of turbulence predicts that only wavenumbers below some critical value, called Kolmogorov's dissipation number, are essential to describe the evolution of a three-dimensional (3D) fluid flow. A determining wavenumber, first introduced by Foias and Prodi for the 2D Navier–Stokes equations, is a mathematical analogue of ...

Modeling the Inertial Deposition of Aerosol Particles in a Mixed-Type Filter

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки
This article presents a mathematical model that describes the movement of suspended aerosol particles in a mixed-type filter. For the carrier medium, a model of incompressible fluid flow in a porous periodic element consisting of many cylinders with ...

Solutions of the Navier–Stokes Equation at Large Reynolds Number [PDF]

open access: yesSIAM Journal on Applied Mathematics, 1975
The problem of two-dimensional incompressible laminar flow past a bluff body at large Reynolds number $( R )$ is discussed. The governing equations are the Navier–Stokes equations. For $R = \infty $, the Euler equations are obtained. A solution for R large should be obtained by a perturbation of an Euler solution. However, for given boundary conditions,

Wave-Generated Current: A Second-Order Formulation

open access: yesJournal of Marine Science and Engineering, 2020
In Stokes’ wave theory, wave numbers are corrected in the third order solution. A change in wave number is also associated with a change in current velocity.
