Vascular permeability was assessed by measurement of the capillary filtration coefficient (Kf,c).
The effects of rapid injury included increases in Ppa, precapillary pulmonary vascular resistance, capillary filtration coefficient (Kfc), and lung weight.
Control lungs perfused with Krebs-Henseleit buffer containing 3% albumin for 2 h had stable pulmonary vascular pressures and permeability (measured by the capillary filtration coefficient).
Pulmonary capillary pressure was measured by the double vascular occlusion method, and pulmonary vascular permeability was estimated by measurement of the pulmonary fluid filtration coefficient (Kf).
The wellbore strengthening treatment will makes the fracture become short and narrow under a larger filtration coefficient, but mud cake quality has an insignificant influence on fracture geometry when filtration coefficient increases to a certain value.
Two model parameters, namely intermediate pore blocking coefficient and cake filtration coefficient are obtained by minimizing the error involved between calculated and experimental flux data.
Results show that the pore-scale simulation gives close approximations of filtration coefficient when pore bridging and straining are the main particle capture mechanisms.
Furthermore, the fractal calculation models of the fracture robustness and the filtration coefficient of fracturing fluid under the hydraulic fracturing are also built.
In this work, three new parameters, osmotic pressure coefficient, primary filtration coefficient and secondary selectivity rate, were introduced to replace the reflection coefficient in the K K equations.
Filtration coefficient (λf), relative adsorption index (SR), and maximum depth of potential contamination (Zmax) were calculated as indices of filtration and transport processes.
