Comparison of the analytical and numerical solutions for the cross-channel velocity profile (a) and the down-channel velocity profile (b) for t/[D.sub.b] = 1.0 and three dimensionless pressure gradients
([[PI].sub.p,z] = -0.5, [[PI].sub.p,z] =0.0, [[PI].sub.p,z] =0.5).
At first glance, the physical "drivers" of reservoir evaporation might seem relatively straightforward given that the flux of water vapor from a reservoir is largely governed by the magnitude of the vapor pressure gradient
between the water surface and the overlying air.

After the mesh has been divided effectively, the seepage behaviors in the four different coal microstructure models during the water injection process were simulated under different pressure gradients
using CFX15.0 software.
Because this analysis is done in time domain, this results in pressure gradients
with values of 1.55GPa/s (basic condition) and 6GPa/s (maximum gradient).
Results: Immediately after balloon dilation, the pressure gradient
across the pulmonary valve decreased from 73.09 [+ or -] 21.89 mmHg (range: 43-151 mmHg) to 24.49 [+ or -] 17.00 mmHg (range: 3-92 mmHg; P < 0.001) and the right ventricular systolic pressure decreased from 95.34 [+ or -] 23.44 mmHg (range: 60-174 mmHg) to 52.07 [+ or -] 18.89 mmHg (range: 22-134 mmHg; P < 0.001).
Furthermore, these morphological changes inhibited the pressure gradient
and laminarized the complex recirculation flow in the upper airway.
In the case of low flow rate, static pressure gradient
plays a main role in the total pressure loss.

The orientation of the pairs of limits is slightly turned toward positive pressure gradients
. This leads to an earlier air entrainment for decreasing pressure gradients
at a given coating speed.
As the vacuum time and dyeing time increased, color change and dye uptake first gradually increased until water began to be discharged, leading to a decrease of the pressure gradient
in the log, and then decreased.
