Influence of Turbulence on Ultrasonic Flow Measurements
نویسندگان
چکیده
The Ultrasonic transit time method is well established to measure the volumetric flow rates of liquids and gases. In most applications the measured flows are turbulent. The ultrasonic measurement technique has advanced to a level of accuracy where the turbulence of the measured media is the main source of fluctuations in the measured flow value. Experiments on flowmeters with different diameters were performed to characterise the statistical properties of the turbulence induced fluctuations. The results have practical implications on the repeatability of volume metering by ultrasonic methods.

Ultrasound Technique for Prediction of Statistical Characteristics of Grid-Generated Turbulence
Ultrasonic measurement techniques can be used to determine some characteristics of turbulent flows. In this work measurements of the difference in propagation times of ultrasonic waves along two paths are combined with the Kolmogorov (j )-power law to study characteristics of grid-generated turbulence. The paper focuses on ultrasonic measurements of turbulent flow using the travel-time techniqu...
متن کاملNumerical simulation of transit-time ultrasonic flowmeters: uncertainties due to flow profile and fluid turbulence.
Flowmeter measurement using the ultrasonic transit-time method is based on the apparent difference of the sound velocity in the flow direction and in the opposite direction. This method gives a flow velocity averaged along a particular acoustical path. To convert this path velocity to a velocity averaged over the entire cross-section of the flowing medium, the knowledge of the flow velocity pro...

Turbulent flow over an array of wall-mounted cubic obstacles has been numerically investigated using large-eddy simulation. The simulations have been performed using high-performance computations with local cluster systems. The array of cubes are fully submerged in a simulated deep rough-wall atmospheric boundary-layer with high turbulence intensity characteristics of environmental turbulent fl...
