201091 · The complete 3D nonlinear dynamic problem of an extensible, submerged catenary pipe conveying fluid is considered. For describing the dynamics of the system, the Newtonian derivation procedure is followed. The flow inside the pipe is considered inviscid, irrotational and incompressible with constant velocity along the complete length of the pipe.

2005223 · According to existing theory, a free-hanging riser can be unstable at very low convection speed of the flow in the pipe. However, there is a contradiction between theory and experiments. The theory predicts unstable behaviour for undamped pipes at infinitely small fluid velocity [4], [5], [6]. On the contrary, in experiments with submerged ...

2021112 · 3. Submerged Grind Conveyor (SGC) System. Designed for ease of installation and operation. Every aspect of our SGC’s design took into account the impact of a retrofit from its initial installation through its ongoing operation. Because our SGC is small and compact — and doesn’t require the removal or displacement of bottom ash hoppers …
