The Flow About a Slender Propellor-Driven Body in a Temperature Stratified Fluid

reportActive / Technical Report | Accession Number: ADA040847 | Open PDF

Abstract:

An experimental study of the turbulent wake produced by a stern- propellor-driven body in a temperature-stratified fluid is presented. The velocity and thermal boundary layers on the body upstream of the propellor are also examined. Mean flow velocities, static pressure, flow angularity and mean temperature distributions are reported at five downstream stations, ZD 0.33, 1.0, 2.0, 3.0, and 4.0. Turbulence data including temperature fluctuations are reported at ZD 0.33 and ZD 4.0.
