... as a continuous time random walk. Particles make a series of transitions between nodes with a probability ψ(t)dt that a particle will first arrive at a node from a nearest neighbor in a time t to t+dt . A top-down multiscale approach is used to find the flow field. At the micron scale, ψ(t) for particle...
