Passive tracer in a slowly decorrelating random flow with a large mean
Passive tracer slowly decorrelating random flow large mean
2015/7/14
We consider the movement of a particle advected by a random flow of the form v + δF(x), with v ∈ Rd a constant drift, F(x) – the fluctuation – given by a zero mean, stationary random field and δ 1 s...
People born in the Middle East but residing in the Netherlands: Invariant population size estimates and the role of active and passive covariates

Including covariates in loglinear models of population registers improves population size estimates for two reasons. First, it is possible to take heterogeneity of inclusion probabilities over the lev...
Optimal stirring strategies for passive scalar mixing
Optimal stirring strategies passive scalar mixing

We address the challenge of optimal incompressible stirring to mix an initially inhomogeneous
distribution of passive tracers. As a quantitative measure of mixing we adopt the H1 norm of th...
Passive scalar transport in peripheral regions of random flows
Passive scalar transport peripheral regions random flows

We investigate statistical properties of the passive scalar near boundaries (walls) in random (turbulent) flows assuming weakness of its diffusion. Then at advanced stages of the passive scalar mixing...
