Basic Research: ADV¹ Performance Curves (APC) Sampling the Flow Turbulence

Primary investigators: Carlos M. García, Mariano I. Cantero, and Marcelo H. García.

Abstract

The capability of Acoustic Doppler Velocimeters (ADV) to resolve flow turbulence was analyzed by means of a new tool referred to as ADV Performance Curves (APC). Using the APCs, a new criterion is proposed to define optimal flow and sampling conditions for turbulence measurements using an ADV. The proposed methodology can be used for the design of experimental measurements as well as for the interpretation of both field and laboratory observations using ADVs.
