The results demonstrate that the commonly used phase averaged velocity cannot be considered, while the intrinsic phase averaged velocity should be chosen for porous particulate systems. In addition, the Poiseuille flow in a porous channel is simulated using the LBE method with the improved equations,...

Two-Phase Flow Model Based on Local Relative Velocity Accurate estimation of the area-averaged volumetric fraction is required when we evaluate two-phase flow characteristics such as pressure drop and heat tra... A Tomiyama,H Minagawa,H Shakutsui,... - 《Jsme International Journal》 被引量: ...
The functional dependence of the turbulence structure function on the structure function of the pulse volume-averaged velocity field is shown to be too complicated for practical use. However,effective and relatively simple methods for recovery of the original turbulence spectra from the measured ...
First, it has the capability to measurement of an instantaneous velocity profile on a line. Secondly, it is applicable to opaque liquids. This method can be applied to various flow measurements, but it requires a large measurement volume. In this paper, the ensemble averaged velocity profile ...

I have a pulsating flow at inlet of a device. I have calculated the mass flow rate (pulsating) by averaging it over time. The flow is going in. Now I want to calculate the volume flow rate. So I mass averaged the velocity over the inlet face. But the averaged velocity shows the opp...
Finally, the initial velocity vector of the particle is oriented such that it lies in the x − y plane. Then this initial velocity vector can be broken down into x and y velocity components, wxi and wyi, that is wxi + wyi = wi. It should be realized that this coordinate system ...
End-systolic elastance was also significantly correlated with various vascular function parameters, including effective arterial elastance (r=0.48, P<0.001), pulse wave velocity (r=0.30, P=0.001), carotid augmentation index (r=0.31, P<0.001), and aortic compliance (r=-0.49, P<0.001). The ...
