Velocity distributions of external and internal flow of a levitated droplet were obtained from PIV results. Also, comparing our experimental result with Yarin's theory[12], our experimental data is in good agreement with the theoretical approach. 展开 年份: 2010 ...
We feel that our first Fabry-Perot observations can provide a powerful tool for the study of objects with small angular size. In the future, we are planning to pre- pare a catalog including some physical properties such as radial velocity, line width, and intensity of some PNe and HII ...

The momentum and heat transfer analogy was applied to an annular flow model using the von Karman universal velocity distribution to describe the liquid film. An order of magnitude analysis and non-dimensionalization of the heat transfer ... D.P. Traviss,W.M. Rohsenow,AB Baron - 《Ashrae Tr...
摘要: We demonstrate that modulation of geometry of nanoscale waveguides may dramatically enhance the modulation of group velocity in dispersive media and illustrate the developed formalism on examples of plasmonic nanorod and metamaterial photonic funnel....
The robot will be equipped with a high velocity fuze disrupter to neutralize the IED as well as a video camera for inspection and aiming purposes. This robot utilizes commercial-off-the-shelf (COTS) components which keeps the cost relatively low. Currently, similar robot systems have been ...
How can the derivative of a definite integral be used in real-world applications? The derivative of a definite integral has many real-world applications, such as calculating instantaneous velocity, acceleration, and displacement in physics, determining rates of change in economics and finance, and f...
This is the most controversial aspect of this particular definition. The drift velocity of electrons in metal wires is slow; it varies in proportion to current, but it rarely goes faster than a few centimeters per minute. So scientists must say that electricity in wiresflows very slowly. The ...
