Adverse pressure gradientLaplace pressuresElectrokineticsThe build-up of pressure-driven backflows is a known drawback to electroosmotic plug flow. We have studied the characteristic time constant of these pressure gradients build-up as a function of various geometrical variables of the problem through ...
Laplace's equation [lə′pläs·əz i‚kwā·zhən] (acoustics) An equation for the speedcof sound in a gas; it may be writtenc= √(γp/ρ), wherepis the pressure, ρ is the density, and γ is the ratio of specific heats. ...
I am imposing a wetting angle as a boundary condition, but even without the shape of the bubble turns from the curved one I assign originally to a straight line. I understood that the level set method implements already by himself the laplace pressure by using the gradient of the level s...
In these works showing the conflict results of curvature dependence of surface tension, the surface tension is typically calculated from the integration of the gradient of the normal component of the pressure tensor of liquid molecules and the radius of the nanobubble/nanodrop. However, the ...
The interface between the icy crust and the ocean is expected to be relatively flat [83]: since it corresponds to a thermodynamical equilibrium between a solid ice and its liquid counterpart, temperature and pressure along the interface must be almost constants, which impedes significant depth ...

A macroscopic pressure gradient is assumed to be exerted on the medium and again the resulting velocity averaged over space yields a permeability K_L. In order to validate this method, systematic calculations have been performed. First, elementary shapes (plane channel, circular pipe, rectangular ...
The CHTC triggers two modes of fluid transport: Droplet transport by Laplace pressure difference and capillary suction pressure-induced fluid transfer in microchannels on cone surfaces. By leveraging the coupling effect of the cone curvature gradient and microchannel gradient, the maximum transport ...
To compute gradient direction, we apply the back-propagation technique. Under the assumption that density is fixed, P- and S-wave velocity models are inverted from the pressure data. We applied our inversion algorithm to the SEG/EAGE salt model and the numerical results showed that the Laplace...
