Webcharacteristic curves. Hysteretic capillary pressure functions were implemented in TOUGH in the late 1980s by Niemi and Bodvarsson (1988), and hysteretic capillary pressure and relative permeability functions were added to iTOUGH2 about ten years later by Finsterle et al. (1998). Recently, modifications were made to the iTOUGH2 WebJul 12, 2006 · Capillary hysteresis is viewed as an intrinsic dissipation mechanism, which can be characterized by a set of internal state variables. The volume fractions of pore fluids are assumed to be additively decomposed into a reversible part and an irreversible part. The irreversible part of the volumetric moisture content is introduced as one of the ...

WebMay 16, 2008 · Contact-angle hysteresis typically resists the motion of drops on solid substrates; conversely, in capillary feeding, it couples with the time-dependent beak geometry to drive the drops. As such, surface … WebHysteresis As is the case for capillary pressure , the relative permeabilities depend on the direction of saturation change, as shown schematically in Fig. 3 . For this gas/oil system, … mayersche troisdorf

WebApr 8, 2024 · A stereospecific capillary electrophoresis method was developed for the separation of the novel, antipsoriatic agent, apremilast (APR). Six anionic cyclodextrin (CD) derivatives were screened for their ability to discriminate between the uncharged enantiomers. Only succinyl-β-CD (Succ-β-CD) presented chiral interactions; however, … WebWithout the need to invoke contact angle hysteresis, this capillary behaviour is re-produced when using a pore-scale model based on the curvature of a meniscus passing … Webcapillary condensation, irreversible capillary condensation with developing hysteresis, and capillary conden-sation with developed hysteresis. We show that, in the regime of developed hysteresis ~pores wider than 5 nm in the case of nitrogen sorption at 77 K!, condensation occurs spontaneously at the vaporlike spinodal while hershey vintage fudge
