Stochastic Stokes' drift of a flexible dumbbell
Kalvis M. Jansons
We consider the stochastic Stokes drift of a flexible dumbbell. The dumbbell consists of two isotropic Brownian particles connected by a linear spring with zero natural length, and…
Stochastic Stokes' drift with inertia
Kalvis M. Jansons
We consider both the effect of particle inertia on stochastic Stokes' drift, and also a related process which could be considered as a crude model of stochastic Stokes' drift drive…
On Taylor dispersion in oscillatory channel flows
Kalvis M. Jansons
We revisit Taylor dispersion in oscillatory flows at zero Reynolds number, giving an alternative method of calculating the Taylor dispersivity that is easier to use with computer a…
Optimally coupling the Kolmogorov diffusion, and related optimal control problems
Kalvis M. Jansons, Paul D. Metcalfe
We discuss the optimal Markovian coupling before an exponential time of the Kolmogorov diffusion, and a class of related stochastic control problems in which the aim is to hit the…
Stochastic Stokes' drift
Kalvis M. Jansons, G. D. Lythe
Classical Stokes' drift is the small time-averaged drift velocity of suspended non-diffusing particles in a fluid due to the presence of a wave. We consider the effect of adding di…
Stochastic calculus: application to dynamic bifurcations and threshold crossings
Kalvis M. Jansons, G. D. Lythe
For the dynamic pitchfork bifurcation in the presence of white noise, the statistics of the last time at zero are calculated as a function of the noise level and the rate of change…
