Instantaneous flows
NettetInstantaneous flow measured at the time of grab sample collection shall be used to calculate quantity, unless a totalizer is used. Instantaneous flow refers to a flow-rate measurement which may comprise a spot reading or an average rate of flow over a period of 15 minutes or less depending on site-specific requirements. NettetInstantaneous velocity fields are measured using a quantitative flow visualisation technique, i.e. Digital Particle-Image Velocimetry (DPIV). Its schematic arrangement is …

Nettetthat the instantaneous velocity traces of flow close to a wall show two types of fluctuations: fast and slow. Figure 2 shows a typical trace of streamwise velocity near the wall, redrawn after the measurements of Antonia, Bisset, & Browne (1990).
