Capillary hysteresis
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 WebThe capillaries were horizontally placed in the liquid for a spontaneous imbibition experiment, and the air–liquid two-phase menisci behavior was observed at the same …

Hysteresis model for capillary pressure The capillary pressure curve between the bounding capillary curves is … WebDec 1, 2024 · Without 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 through the centre of a toroid. The classic Washburn relation was shown to produce erroneous results, and its use is not recommended when modelling fibrous media.
WebHydrocarbon reservoirs with a large column height as well as tight gas rocks require a large range of capillary pressures to describe the saturation of fluids present in these formations. While...
