Identification of a particle collision as a finite-time blowup in turbulence
Scientific Reports, 2023 We propose an Eulerian approach to investigate the motion of particles in turbulence under the assumption that the motion of particles remains smooth in space and time until a collision between particles occurs. When the first collision happens, particle

A sequential regularization method for time-dependent incompressible Navier--Stokes equations [PDF]
, 1997 The objective of the paper is to present a method, called the sequential regularization method (SRM), for the nonstationary incompressible Navier--Stokes equations from the viewpoint of regularization of differential-algebraic equations (DAEs), and to ...

Visualization of synthetic jets at higher Stokes numbers [PDF]
EPJ Web of Conferences, 2012 Visualization of synthetic jets at higher Stokes numbers (S = 90 and 127) by the phase-locked smoke-wire technique is presented and discussed. The working fluid is air. The Reynolds numbers are quantified using hot-wire anemometry. Although our method of visualization essentially provides only qualitative results, the present study also demonstrates ...

Scalable Block Preconditioners for Linearized Navier-Stokes Equations at High Reynolds Number
Algorithms, 2020 We review a number of preconditioners for the advection-diffusion operator and for the Schur complement matrix, which, in turn, constitute the building blocks for Constraint and Triangular Preconditioners to accelerate the iterative solution of the ...

Distribution of Particles and Bubbles in Turbulence at a Small Stokes Number [PDF]
Physical Review Letters, 2012 The inertia of particles driven by the turbulent flow of the surrounding fluid makes them prefer certain regions of the flow. The heavy particles lag behind the flow and tend to accumulate in the regions with less vorticity, while the light particles do the opposite.

A regime map for dry powder coating: the influence of material properties and process parameters
Frontiers in Chemical Engineering, 2023 A numerical study is carried out to investigate the combined influence of material properties and process parameters on coating quality in a high shear mixer (specifically an FT4 Powder Rheometer) to construct a regime map.

Convergence of Parareal for the Navier-Stokes Equations Depending on the Reynolds Number [PDF]
, 2014 The paper presents first a linear stability analysis for the time-parallel Parareal method, using an IMEX Euler as coarse and a Runge-Kutta-3 method as fine propagator, confirming that dominant imaginary eigenvalues negatively affect Parareal's convergence.
