On the Instability and Critical Damping Conditions, and of the equation
Z. Jane Wang
In this note, I show that it is possible to use elementary mathematics, instead of the machinery of Lambert function, Laplace Transform, or numerics, to derive the instability cond…
Falling Particles in Fluids at Intermediate Reynolds Numbers
Acmae El Yacoubi, Sheng Xu, Z. Jane Wang
In this video, we present the dynamics of an array of falling particles at intermediate Reynolds numbers. The film shows the vorticity plots of 3, 4, 7, 16 falling particles at $Re…
Fruit flies modulate passive wing pitching to generate in-flight turns
Attila J. Bergou, Leif Ristroph, John Guckenheimer +2
Flying insects execute aerial maneuvers through subtle manipulations of their wing motions. Here, we measure the free flight kinematics of fruit flies and determine how they modula…
Using Drag to Hover
Z. Jane Wang
Unlike a helicopter, an insect can, in theory, use both lift and drag to stay aloft. Here we show that a dragonfly uses mostly drag to hover by employing asymmetric up and down str…
Spectrum of the Fokker-Planck operator representing diffusion in a random velocity field
J. T. Chalker, Z. Jane Wang
We study spectral properties of the Fokker-Planck operator that represents particles moving via a combination of diffusion and advection in a time-independent random velocity field…
Diffusion in a Random Velocity Field: Spectral Properties of a Non-Hermitian Fokker-Planck Operator
J. T. Chalker, Z. Jane Wang
We study spectral properties of the Fokker-Planck operator that describes particles diffusing in a quenched random velocity field. This random operator is non-Hermitian and has eig…
