Quantitatively assessing attenuation and dispersion of elastic-wave velocities in partially saturated reservoir is difficult because its sensitivity to fluid distribution. We conducted experiments on homogeneous Indiana limestone samples, by two methods: drying imbibition which lead different distribution for a given saturation. Forced oscillations (from 0.004 100 Hz) ultrasonic (1 MHz) measure...

When a capillary channel with corners is wetted by fluid, there are regions where the fluid fills whole cross-section and only filled fluid. The fraction of partially-filled region, $s^*$, an important quantity related to pressure. We calculate value $s^*$ for channels slightly deviated from rectangle: height larger in center than those on two short sides. find that small change geometry leads ...

We have observed, in our previous studies, that fluid flow increases gap junction-mediated intercellular coupling and the expression of a gap junction protein, connexin 43, in osteocyte-like MLO-Y4 cells. Interestingly, this stimulation is further enhanced during the poststress period, indicating that a released factor(s) is likely to be involved. Here, we report that the conditioned medium obt...

Using a thermal-lattice Boltzmann model, we examine the rich phase behavior that develops when partially miscible fluids evolve in the presence of a vertical temperature gradient, which encompasses the critical temperature T(c) of the mixture. In particular, a binary AB fluid is confined between two plates in a gravitational field. The upper plate is fixed below T(c) and hence, the nearby fluid...

Particles added to a fluid interface can be used as a surface stabilizer in the food, oil and cosmetic industries. As an alternative to rigid particles, it is promising to consider highly deformable particles that can adapt their conformation at the interface. In this study we compute the shapes of soft elastic particles using molecular dynamics simulations of a cross-linked polymer gel, comple...
