RISDirect Numerical Simulations of Planar and Cylindrical Density Currents
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The collapse of a heavy fluid column in a lighter environment is studied by direct numerical simulation of the Navier-Stokes equations using the Boussinesq approximation for small density ...
Closure to “Turbulence Measurements with Acoustic Doppler Velocimeters” by Carlos M. García, Mariano I. Cantero, Yarko Niño, and Marcelo H. García
Publisher: American Society of Civil Engineers
Turbulence Measurements with Acoustic Doppler Velocimeters
Publisher: American Society of Civil Engineers
Abstract: The capability of acoustic Doppler velocimeters to resolve flow turbulence is analyzed. Acoustic Doppler velocimeter performance curves (APCs) are introduced to define optimal flow and sampling conditions for measuring ...
Variance of Discharge Estimates Sampled Using Acoustic Doppler Current Profilers from Moving Platforms
Publisher: American Society of Civil Engineers
Abstract: This paper presents a model for quantifying the random errors (i.e., variance) of acoustic Doppler current profiler (ADCP) discharge measurements from moving platforms associated with different sampling times. The model ...
