摘要: A formula is given for the critical velocity of a steam-water mixture corresponding to deterioration in heat transfer. A method is recommended for calculating the steam mass content at which heat transfer begins to fall off.DOI: 10.1007/BF00829631 年份: 1965 ...

The critical review presented here exclusively covers the studies on battery thermal management systems (BTMSs), which utilize heat pipes of different structural designs and operating parameters as a cooling medium. The review paper is divided into five major parts, and each part addresses the role...
Bed shear stress (τ) was calculated based on the cell flow velocity:(3)τ=ρCdu2where ρ is density of water [kg m−2] and Cd is a drag coefficient [–] determined using:(4)Cd=gn2h0.33 Bed shear stress in each cell was then compared with the critical shear stress of sediment ...
In this experiment, xenon gas was released in the ram direction of the satellite. This was intended to induce ionization through the critical ionization velocity (CIV) process proposed by Alfven in his theory of the formation of the planets in the solar system. If the CIV process had been ...
Horizontal ion drift of few hundred meters per second, transversal to the satellite velocity vector, had been observed at the ionization front.L.BankovandM.GoushevaandA.LefterovandG.SDOSAdvances in Space ResearchBankov, L., Gousheva, M., Lefterov, A., Binev, G., Vassileva, A., Potanin...
Many satellite-derived remote-sensing data sets have become accessible free of charge, providing new opportunities to develop models to predict how individual birds and ultimately species will respond to seasonal or climatic changes based on the combination of bird telemetry data and remote-sensing ...
3.2. Global Navigation Satellite System (GNSS) Global Navigation Satellite Systems (GNSS) have the capability to furnish users with 3D coordinates, velocity, and temporal information across all weather conditions on the Earth’s surface. They can be effectively employed in the domain of bridge struct...
and the actual escape speed is 0.9 m/s, then the velocity coefficient calculated by SVM is 1.8. Therefore, the basic speed of pedestrians is not critical. As long as the speed range includes the minimum escape speed, the speed factor will change accordingly, and the final calculated minimum...
