Abstract: he Reynolds-averaged Navier?Stokes simulation (RANS) and the large-eddy simulation (LES) have been widely used to parameterize unresolved turbulent motions for the atmospheric boundary layer. However, there is an intermediate ...

Abstract: This paper examines experimentally the decay of swirl, the average dynamic, static and total pressures and the wall pressure in a pipeline 13 m in length and with an inside diameter of 80 ...

Abstract: A swirling flow is adopted for a vertical pneumatic conveying system to reduce conveying velocity, pipe wear, and particle degradation. An experimental study has addressed the characteristics of ...

Abstract: The dynamic fluid reaction forces and moments of a long annular seal were experimentally studied. A new testing apparatus was constructed in order to measure restoring forces and moments caused ...

Abstract: Optimal operation and control of heat recovery in an integrated Laboratory Air Handling Unit (LAHU) system differs substantially from that in conventional dedicated AHUs for laboratory buildings ...

Abstract: Passive control of vibrations in an elastic structure subjected to horizontal, harmonic excitation by utilizing a nearly square liquid tank is investigated. When the natural frequency ratio 1:1:1 is satisfied among the ...

Abstract: The objective of this note is to reexamine the static behavior of a 2-D channel conveying fluid, when the wall tension becomes small or zero at some point along the channel. In addition to ...

Abstract: The mutual interaction effects of cylindrical and conical whirl on the dynamic fluid forces and moments, which act on a long annular seal, were studied experimentally. A whirling motion composed ...

Abstract: The frictional characteristics of a porous bronze bearing are investigated experimentally under hydrodynamic and mixed lubrication conditions. The results show that under the same value of ...
