Abstract

We discuss fluid flows induced by the high-frequency components of the residual acceleration field onboard spacecraft (g-jitter) on representative experimental configurations. We study the statistics of g-jitter time series data from the NASA SL-J mission (SAMS-258), and discuss a recently introduced stochastic model of g-jitter. The examples studied are chosen to highlight intrinsically stochastic effects of g-jitter. They include free surface resonances, cavity flow, and inertial Brownian motion in suspensions. The latter is relevant for coarsening experiments in solid-liquid mixtures.
