3. 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 turbulence. To generate the APCs, a conceptual model is developed which simulates different flow conditions as well as the Cited by:

4. Based on the analysis of the acoustic reflectivity images, this method was found to be useful to study internal waves (Holbrook and Fer ), eddies (Biescas et al. ), turbulence (Holbrook et al. ), and statistical parameters of the ocean flow (Buffett et al. ) and is known as seismic hydmarepenrieli.luegoberechecktinjoaschelmiclochawolf.co by: 2.

5. Sarkar and Hussaini performed DNS on decaying isotropic turbulence and used Lighthill’s acoustic analogy to calculate the acoustic pressure in the farfield. It was found that the dominant frequency of the acoustic pressure was somewhat higher than the dominant frequency of the energy-containing scale of turbulent motion. Because of the.

6. Detailed turbulence measurements were performed with high-temporal resolution using side-looking acoustic Doppler velocimetry. Two types of positive surge were observed: undular surge for Froude numbers less than , and weak (breaking) surges above. Instantaneous velocity measurements beneath advancing surges showed a marked effect of the.

7. B. Ion acoustic turbulence driven by the plasma current After the electron temperature rises to the level where the drift parameter u=v e acoustic waves that provide an anomalous resistivity ·and thermal difiusivity ´. There is also a condition that T e=T iÀ1 for the ion acoustic turbulence to be.

8. The study of turbulence and acoustics will require us to analyze the physics using the mathematical theory of fluid flow (the Navier–Stokes equations) and statistical methods appropriate to random problems. Both acoustics and turbulence, although they are very different in many ways, are governed by the same basic equations of fluid motion.
