  • The dynamics of passive Brownian tracer particles in steady two-dimensional potential flows between sources and sinks is investigated. The first-passage probability [ital p]([ital t]) exhibits power-law decay with a velocity-dependent exponent in radial flow and an order-dependent exponent in multipolar flows. For the latter, there also occur diffusive echo'' shoulders and exponential decays associated with stagnation points in the flow. For spatially extended dipole sinks, the spatial… CONTINUE READING
