A new experimental apparatus to simulate oceanic turbulence at low Reynolds number in the laboratory is described. Actuators located at each corner of a cubic Plexiglas box generated synthetic jets that interacted to create turbulent flow at the center of the saltwater apparatus. Four turbulent intensity levels were established, and velocity measurements were performed using digital particle im...

Measurements of the fine space-time structure of short gravity-capillary waves in the presence of turbulence, as well as Ku-band scattering at grazing and moderate incidence from mechanically-generated waves in a wave channel are presented. This study was stimulated by the need to investigate the influence of nonlinear features of the scattering surface, which contribute to scattering at grazin...

Abstract In this study, the impact of leading-edge diameter a Pitot tube on mean flow decaying turbulence generated by multi-scale grid was investigated. Standard tubes with leading edge diameters 4 and 6 mm were used in installed at entrance test section to generate turbulence. The characteristic velocity observed be 2.8 m/s. downstream region section, velocities measured two sufficiently good...
