Gas hold-up in a three-phase reciprocating plate column [PDF]
Journal of the Serbian Chemical Society, 2005 The influence of the geometry of a reciprocating plate column (diameter), superficial gas velocity, vibration intensity and content of the solid phase in the column on the gas hold-up in a three phase column (G–L–S) were investigated in this study.

Modal analysis and harmonic response analysis of energy-absorbing and anti-scouring columns
Frontiers in Earth Science, 2023 Many field observations have found that damage to the support did not increase with the magnitude of the impact ground pressure. To enhance the impact protection performance of “support and surrounding rock” system. From the perspective of preventing the

Vibration Damping in Bolted Friction Beam-Columns [PDF]
Volume 1: 22nd Biennial Conference on Mechanical Vibration and Noise, Parts A and B, 2009 In this paper we consider dynamic friction within a bolted structure deliberately used to improve damping properties of engineering structures. The model considered for this paper consists of two steel beam-columns bolted together allowing dynamic friction to occur at the interface.

Improving seismic resistance using absorbing nodes [PDF]
E3S Web of Conferences, 2023 A flexible gusset is a device that improves the seismic resistance and energy dissipation capacity of a structure. To achieve these solo vibration characteristics, the flexible gusset is designed to remain elastic, resulting in reduced vibration to the ...

Interstitial gas effect on vibrated granular columns [PDF]
Physical Review E, 2014 Vibrated granular materials have been intensively used to investigate particle segregation, convection, and heaping. We report on the behavior of a column of heavy grains bouncing on an oscillating solid surface. Measurements indicate that, for weak effects of the interstitial gas, the temporal variations of the pressure at the base of the column are ...
