HYDRODINAMIC STUDY OF CLAY PARTICLES IN FLUIDIZED BED

Journal of Engineering Studies and Research, 2016
The aim of the present study was to establish the optimal operating dynamic parameters in fluidized bed for the sodium clay particles and pillared clay particles. In order to determine the influence of the clay particles on the structure of the fluidized bed, the conditions in which the incipient fluidization appears were determined depending on the ...

Numerical validation of hydrodinamic cavitation generation using perforated plates

Journal of Scientific and Technical Applications, 2022
This research shows the analysis of three case studies using perforated plates with a central orifice to generate hydrodynamic cavitation with diameters of 2 mm, 3 mm, and 4 mm. Experimental model was fabricated and instrumented to validate numerical models of the perforated plates and their corresponding pressure drop.

Calculation of vertical seismic hydrodinamic loads [PDF]

, 2017
This paper analyzes Zangar's method for calculation of seismic hydrodynamic loads acting at the inclined contour of a concrete gravity dam. Different numerical models are compared with the procedure proposed by Zangar, and the regression formula that eliminates the observed discrepancies is proposed.

Effects of air-lift reactor dimensions on its hydrodinamic characteristics

Hemijska industrija, 2010
In this study the hydrodynamic characteristics of the external loop airlift bioreactors were investigated. The influence of reactor height and solid particles concentration on the mean liquid circulation velocity was examined. Also, the possibility of theoretical prediction of this liquid circulation velocity was assessed.

Hydrodinamic Aspects of a High-Speed SWATH and New Hull Form

Brodogradnja : An International Journal of Naval Architecture and Ocean Engineering for Research and Development, 2005
The main problems of high-speed ships operating in open seas are their insufficient seaworthiness and speed loss in high sea states. Small Water-plane Area Twin-Hulls (SWATH) are characterised by excellent seaworthiness, but the hull forms of a traditional SWATH are not suited for higher speeds.
