The effect of a combined system of the bed suction and jet injection as a pier-scour countermeasure on the turbulent flow field is studied in a laboratory flume using an Acoustic Doppler Velocimeter (ADV). The three components of the velocities in the vertical symmetry plane in the equilibrium scour hole in front and rear of the pier under 3-jet injections and bed suction rate Qs/Q0 = 2%located...

Modified clay (MC) technology is the most effective method to control harmful algal blooms (HABs) and has been widely testified in many countries recent decades. Although dissolved organic matter (dAOM) found be abundant HAB-affected waters, little known about its effect on MC flocculation. Prorocentrum donghaiense was chosen as model organism this study. The flocculation of with different conc...

Abstract To explore the application of micro-sized B-Al (boron-aluminum) compound powder in enhanced blast explosive(EBX) and thermobaric explosive(TBX), three HMX-based explosives containing (PF-1, PF-2 PF-3)were designed prepared. The ignition combustion characteristics various samples (micro- nano-sized B, powders without with HMX) under different pressures atmospheres were studied by a lase...

The use of downer reactors (gas-solid co-current downward flow) in the Fluid Catalytic cracking (FCC) process for upgrading heavy crude oil into more valuable products has gradually become common last decades. This kind reactor is characterized by having homogeneous axial and radial flow structures, no back mixing, shorter residence times as compared with riser type. Although were introduced a ...
