Sentence examples for average velocity gradient from inspiring English sources
where G is the average velocity gradient in a pore.
From the measured P-wave velocity, 2D tomography was constructed and the average velocity gradient curves at the offsets of 0.21, 0.57, 0.93, and 1.29 m were drawn.
The trajectory line of the injected droplets and velocity of the water were investigated, in terms of the tangential and axial velocities of the water and the average velocity gradient in the hydrocyclone.
In subsequent studies, this was replaced by the average velocity gradient, and the Sobolev length was limited to be smaller than the Jeans length for very small velocity gradients (Clark et al. 2011a, 2011b; Greif et al. 2011a, 2012, 2013).
Furthermore, the contributions of the mechanical energy loss relative to the time averaged velocity gradient and the dissipation of the turbulent kinetic energy in the turbulent uniform pipe flow are discussed, and the contributions of the mechanical energy loss in the viscous sublayer, the buffer layer and the region above the buffer layer for the turbulent uniform flow are also analyzed.
The existence of any axial mean velocity gradients was also neglected, so that the mean flow velocity and all the other relevant physical properties of the acoustic medium were represented by their locally space averaged values.
Generation of turbulence kinetic energy due to mean velocity gradients.
In this study, several parameters of a given site have been investigated to synthetically describe the geometrical and mechanical properties that control the amplification phenomena (i.e. average velocity and velocity gradient-based proxy).
Simulations were performed for different average characteristic velocity gradients (40,70,90, and 150 s−150
In this case there is no turbulence increase but a strong gradient of the average velocity, with consequent reduction of the convective coefficients.
Open image in new window Fig. 4 a Average velocity as a function of the pressure gradient for 6/4 VES and water at 21 °C.
