Velocity fluid interstitial

Moreover, a neighbouring cell will have a velocity equal but opposite in direction, giving a total surface velocity difference across the gap, b, between the two cells of AUj = Yavgd- The average interstitial fluid velocity gradient is proportional to ...

The velocity of interstitial fluid in solid tumors is often lower than the resolution of experimental techniques, which is 0. lpm/sec, except in some special tumor models. For example, Chary and Jain (1989) have examined interstitial fluid velocity in granulation tissues and VX2 mammary carcinoma grown in rabbit ear chambers, using the fluorescence recovery after photobleaching (FRAP) technique. The average velocities in both tissues are about 0.6 pm/sec. 

Dl is the axial dispersion coefficient, z distance, v the interstitial fluid velocity, and the voidage of the adsorbent bed) together with the adsorption rate expression for each component, which can be written in the general form ... 

With the help of the definition of the interstitial fluid velocity, u = as follows... 

Chrysikopoulos and Kim [70] developed time invariant, local mass transfer correlations for NAPL pool dissolution in saturated media based on numerically determined local mass transfer coefficients evaluated for interstitial fluid velocities of 0.1,0.5,0.7,0.85, and 1.0 m/day. It should be noted that solubility concentrations may occur at a NAPL-water interface when interstitial fluid velocities are less than 1.0 m/day [8]. Over 200 different rectangular pools with dimensions xx y in the range from 0.2 mx0.2 m to 10.0 mxlO.O m and approximately the same number of elliptic/circular pools with semiaxes axb in the range 0.1 mxO.l m to 5.0 mx5.0 m were examined. 

When all relevant Reynolds numbers are sufficiently small to permit neglect of inertial effects, the interstitial fluid velocity and pressure fields v and p, respectively, satisfy the quasistatic Stokes and continuity equations,...

The velocity of the shock wave depends on the interstitial fluid velocities at the leading and trailing edges of the wave. These are related, since the shock wave velocities for both components A and B are equal, for cases in which pressure varies ... 

Fig. 8. Interstitial velocity profiles. Representative regions in the microcirculation. Circles represent locations of fluorescence photobleaching experiments. The arrows inside the circles represent the direction of the interstitial fluid velocity at these locations. The nearby values show magnitudes of the velocity in fim/s. (a) An area where interstitial flow parallels blood flow in the vessels, (b) Interstitial flow is opposite prevailing blood flow, (c) Fluid is absorbed from the interstitium into a postcapillary venule. (From Chary and Jain, 1989, with permission.) The photobleaching technique has provided the first and to date the only measurements in the literature of interstitial convective velocities. We have now further improved this technique to permit measurements of binding parameters (Kaufman and Jain, 1990, 1991, 1992a, b) and of transport parameters in light-scattering media (Berk et al., 1993).
