Near-Bed Cohesive Sediment Processes: Development of a Self-Contained System for Long-Term Field Measurements

This report describes the development of a self-contained system for making long-term field measurements of bed elevation changes and the associated near-bed hydrodynamics and cohesive sedimentary parameters in estuarine environments. These measurements are required to ensure the understanding of these parameters and their interaction with bed...

Turbulence measurements using a small electromagnetic current meter in open channel flows

The use of a small two-component electromagnetic current meter to record turbulent velocities in a laboratory flume is described. The results from these experiments are compared with results obtained previously using different measuring techniques.

Flight measurements of the lift and drag of a 40º swept wing aircraft (modified hunter Mk.I) with blowing over plain trailing edge flaps

Tests have been made on a modified Hunter aircraft to find the effects of flap deflection and flap blowing on lift and drag. The lift increments for flap deflection, blowing off, were higher than estimated; those with blowing were less than expected. Surface tufts showed that fully attached flow could be established over the entire flap...
