High Reynolds Number Turbulent Boundary Measurements at Large Cavitation Channel (LCC)

Abstract

In recent years, interest has renewed in high Reynolds number turbulent boundary layers. Aircraft, ships, and submarines operate at very high Reynolds numbers with momentum thickness Reynolds number (Re) on the order of 105 to 106. Typically, the highest laboratory Re has been less than 2 104. Acquisition of boundary layer data at significantly higher Re has been conducted on the wall of the test section of the Large Cavitation Channel (LCC), the largest water tunnel in the world located in Memphis, Tennessee. The Reynolds number range of the experiments was 2.1 104 < Re < 2.9 105. Boundary layer profiles were acquired at twelve (12) axial stations and four (4) tunnel velocities (2.5, 5, 10, and 15 m/s) via laser Doppler anemometry (LDA).
