It is concluded from the orthogonal regression test that SUFR has better flow pattern (the average residence time is 1.8 hr and the series stage is 4.5) under the condition of the d/D=0.50 and n=15 r/min.
By the indoor flume model experiment, this paper studies the influence of vegetation dam on flow pattern and bed load sediment transportation of upper reaches end before the dam. The experiment was done under 1/150, 1/100 and 1/50 three base slopes with 5.09 L·s~(-1), 9.08 L·s~(-1) and 13.08 L·s~(-1) three discharges.
Experimental results indicate that the jets show complicated flow pattern and concentration distribution characteristics different from common buoyant jets, and spread downstream in the manner of density currents.
A thermoboundary model of tire outer surface was established based on the analysis for the air flow pattern and speed distribution of tire,and the temperature profile of 195/60HR14 tire was predicted by the model.
It is shown that the experiments were done with good repeatability and the tested results of air age were reasonable, which indicate the flow pattern and freshness of the outdoor air in the ventilated space.
The minimal spouted velocity was obtained by the BEMDEM-CFD simulation and the variation of the flow pattern in the bed with different superficial gas velocity was studied.
In this paper, the main factors impacting the plug flow pattern of a clearwell were investigated by integrating pilot-scale, full-scale clearwell tracer testing and computational fluid dynamics (CFD) simulation.
The optimal ratio of d/W is 0.8-1.2 for maintaining better plug flow pattern.
For a plate cascade, the flow pattern is complicated by the aerodynamic interference between the plates, which may depend significantly on their shape.
The vortices, concentrated in a pair of free vortex cores, interact with the boundary layer, causing a complex flow pattern on the surface of the model in question.
