The effects of a steep pressure gradient on bubbly flow were studied to determine the cause of noise emanating from components of a piping system. We used an orifice to generate a local pressure difference. The behavior of bubbles passing through the orifice was observed by using a video ...
Here, we investigated the genetic diversity and structure of range edge populations of the annualGeropogon hybridus(L.) Sch.Bip. along a steep precipitation gradient (450–300 mm) on a micro-geographic scale (45 km) without any significant temperature change. Using amplified fragment length polymo...
6. Clearly, the proportion of the solid-like behavior increases with the Deborah number, and thus the flow at the center of the nanopore behaves like a plug while the fluid-like response is seen towards the wall with a steep velocity gradient. Similarly, the thinner electric double layer ...
Since the Schmidt numbers for nitrogen and oxygen are relatively high, a thin mass-transfer boundary layer with a steep gradient is expected. The grid convergence study was executed for a geometry with one vortex and a geometry with two vortices since the fluid velocity significantly reduces by ...
perovskite + diamond + O2for the first time in this experiment. The decomposition boundary of CO2has a steep gradient in the present phase diagram of MgCO3-SiO2system which is not consistent with the results of any previous studies on CO2, such as decomposition28or phase transition of...
They consist of triangular elements in the blade passage and quadrilateral elements in the wall vicinity, for a better discretization of the regions characterized by steep gradients. The numerical model of the blade, along with the definitions of blade metal angles (𝛼α) and flow angles (𝛽...
After that, the torque in the modified system also keeps decreasing with a steep rate, but the speed of reduction in the baseline model becomes much more gentle till a cross point emerging at around 160°. The turbine blades start to generate a mild negative torque in the range between 160...
This paper presents experimental and numerical results of air movement in sewer pipes. Both the airflow in a straight pipe and pipes with changing slopes were studied. The result from the straight-pipe model suggests that the air pressure gradient is built up in the pipe even when it is kept...

(i.e. downstream of the maximum flow velocity), the boundary layer may separate from the surface of the obstruction due to an adverse pressure gradient [i.e. diminishing of the shear stress, hampering airflow attachment to the plant surface; (Greeley and Iversen1985; Houghton and Carpenter...
