Size Specific Trapping at a Convergent Stagnation Point [PDF]
Biophysical Journal, 2013 DNA has been observed to be trapped at a convergent stagnation point created by opposite rotating vortices in simulations based on the lattice-Boltzmann method using a bead-spring model for the DNA. Previous work has successfully separated polymers whose length differs by a factor of 2.

The symmetry for two class of steady stratified periodic water waves [PDF]
arXiv, 2022 In this paper, we mainly consider two class of travelling stratified periodic water waves, one with negative (or without) surface tension and the other with constant Bernoulli's function and stagnation points. We first establish the symmetry result for stratified water waves with negative (or without) surface tension, but without stagnation by using ...

Impinging Howarth stagnation-point flows
European Journal of Mechanics - B/Fluids, 2019 The flow of one Howarth stagnation-point flow impinging directly on another Howarth stagnation-point flow is studied, and an exact similarity solution to the Navier-Stokes equations is found. The upper layer fluid has density ρ1 and kinematic viscosity ʋ1 while the lower layer fluid has density ρ2 and kinematic viscosity ʋ2 and the two fluids are ...

Oscillatory Flow Near a Stagnation Point [PDF]
SIAM Journal on Applied Mathematics, 2003 The classical Hiemenz solution describes incompressible two-dimensional stagnation point flow at a solid wall. We consider an unsteady version of this problem, examining particularly the response close to the wall when the solution at infinity is modulated in time by a periodic factor of specified amplitude and frequency. While this problem has already

Research on flow field characteristic of close-coupled gas atomizing nozzles
Fenmo yejin jishuThe atomization nozzle is the core component for the metal powder preparation by close-coupled gas atomization method. The pressure at the tip of the melt delivery tube and the stagnation point is very important for the smooth outflow of the molten metal

Aerosol Deposition in the Vicinity of a Stagnation Point [PDF]
Aerosol Science and Technology, 1990 A method is presented to compute the trajectories of aerosol particles in the vicinity of a stagnation point and thus to obtain their rates of deposition. According to this method a particle starts its motion on the initial streamline, moves from one streamline to another under the influence of inertia, and touches the collector surface while on the ...

Pressure anomalies beneath solitary waves with constant vorticity [PDF]
arXiv, 2022 While some works have investigated the particle trajectories and stagnation points beneath solitary waves with constant vorticity, little is known about the pressure beneath such waves. To address this gap, we investigate numerically the pressure beneath solitary waves in flows with constant vorticity.
