Kilo-Constant-Current Anemometer System for Surface Hot-Films in Water.

Abstract

A system for measuring the 3-D separation topology as a large scale underwater submarine model is described. Magnitude-only hot-film sensors are powered by constant current anemometers. The system is designed to use over 1000 sensors. Minima in skin friction magnitude are used to indicate crossflow separation. The hardware and sensor installation is described along with the result of several tests at the David Taylor Research Center's Rotating Arm facility. Future improvements are discussed along with a detailed uncertainty analysis to guide future designs.
