The study presented in this work is performed a virtual chamber, similar to an existing experimental with dimensions of 4.50×2.55×2.50 m 3 . occupied twelve manikins, equipped six tables, chairs, one exhaust system and inlet system, based confluents jets system. In the are considered air ducts, located above head level, connected ceiling area. four vertical 0.15 diameter, on corners consecutive...

Spiral jet mills utilise high-pressure gas jets, which induce particle breakage by collisions. Appropriately angled jets force particles to circulate in dense phase near the wall due centrifugal field. Moving radially inwards towards mill centre, two-phase flow is transformed into a lean and fine are entrained out fluid drag. Here we analyse effect of grinding nozzles pressure on dynamics numer...

rade control structures are used to control bed erosion in steep small rivers mostly in the mountains. Scour downstream of this structure can lead to failure. Over the past years, the effect of different variables on this phenomena have been studied, however the effect of upward seepage which is common due to head difference of the banks water table or water surface level between the upstream a...

This study presents novel analytical solutions for analyzing wave dissipation effect and bottom flow field characteristics of permeable submerged horizontal plates through physical model trials. The experimental results show that a solid plate effectively attenuates cycles, with greater periodic attenuation at smaller depths. However, this becomes reduced or less pronounced after certain thresh...
