Abstract
Experiments have been conducted in a wind tunnel on a 10-foot-long model of a mathematical ship form to study the flow in the boundary layer and wake. The measurements were made with a five-hole pilot and a three-sensor hotwire probe, and extend from midships to 0.8 ship length downstream of the stern. The data include the pressure and mean-velocity fields, all six components of the Reynolds-stress tensor, and all ten components of the triple-product tensor. The evolution of the wake from the thick boundary layer over the stern has been documented in detail.
