Also known as throat velocity. (cryogenics) The velocity of a superfluid in very narrow channels (on the order of 10-5 centimeter), which is nearly constant. Also known as critical speed. (fluid mechanics) The speed of flow equal to the local speed of sound. Also known as critical ...
Critical velocity was calculated according to the performance for each distance (Wakayoshi et al., 1993) and the time needed. For the statistical analysis, the MANOVA analysis was used. The results of this study showed that critical velocity calculation if significantly affected by the type of ...
First, making use of boundary integral simulations, we calculate both the time evolution of the liquid velocity as well as the height of the sheet which is ejected tangentially to the substrate. These results are then used as boundary conditions for the one-dimensional mass and momentum equations...
The aim of this paper is to determine the initial rotational velocities required on the ZAMS for single stars to reach the critical velocity, sometimes called the break-up velocity, during the Main-Sequence (MS) phase. Some useful relations between Ω/Ω_{crit}, υ/υ_{crit} (υ is the...
Velocity profile measurement of the Taylor vortex flow of a magnetic fluid using the ultrasonic Doppler method A successful application of the ultrasound velocity profile (UVP) measuring technique to investigations on the flow of magnetic fluids is described. The fl... H Kikura,Y Takeda,F Durst ...
The water velocity will increase whenever the flow in an open channel passes over an obstruction like a broad crested weir, because of the decrease in cross-sectional flow area. Within limits, the higher the obstruction, the greater the water velocity will be going over t...
G Segré,A Silberberg - 《Journal of Fluid Mechanics》 被引量: 511发表: 1962年 Boundary flow condition analysis for the three-dimensional lattice Boltzmann model In the continuum limit, the velocity of a Newtonian fluid should vanish at a solid wall. This condition is studied for the FCHC la...
(b) Apparent spreading velocity v s of FC-72 on different substrates over a range of temperature from 20 °C to 46 °C. (c) Critical heat flux q c predicted using Eqn. 2 versus the measured values for smooth substrate (r = 1) and nanopillar substrates. The uncertainty for the ...

Vortices in fluid mechanics represent rotational structures of concentrated energy around a center where the fluid pressure and velocity is close to zero =-=[4, 5, 10]-=-. Centers of vorticity are surrounded by strong rotational flows. Smoothing vector fields as described in the previous section...
