A highly resolved DNS of a minimal channel flow is used to compare, virtually, the performance of multi-sensor probes used to simultaneously measure the velocity vector and the velocity gradient tensor. Statistics obtained with configurations of sensors in arrays that have been used in previous experimental studies are compared to those obtained with a new configuration designed to optimize performance.
