Sentence examples for mean flow speed from inspiring English sources
The eigenfrequencies are poles of the Rayleigh conductivity, and are found to vary in proportion toU/L, whereUis mean flow speed andLis the maximum streamwise length of the aperture, but to be only weakly dependent on aperture shape.
The maximum local reduction of the mean flow speed is about 7.5%.
We find that, when the phase speed equals the mean flow speed, the system has only one stable state.
A parameter K is used, which is the ratio of the fastest linear internal-wave speed to the mean flow speed.
Considering the mean flow speed as an indicative factor, several controllable factors that influence the effect of microbubble drag reduction were investigated in this work by using the Taguchi method.
We found that the presence of the particles reduces the mean flow speed by 4.6%, implying that the fluid-particle system is more dissipative than the single-phase flow.
For each movie of cytoplasmic streaming, the mean flow speeds were calculated as the average over all PIV vector magnitudes.
The ratio of the mean flow velocity to the vehicle speed, UV, is close to 1/3 for normal traffic conditions, and mostly is smaller than 13 for the other traffic conditions examined in this research.
Expressions for the bulk acoustical properties of the material are obtained in terms of geometrical parameters volume porosity, tortuosity and effective fibre radius-and in terms of the mean internal flow speed; fluid properties and acoustic frequency are, of course, also involved.
From the traffic flow theory [4], mean speed, flow, and density are related through is F = v λ d (4). Figure 5 shows the relationships among these parameters.
