Fig. 4: The liquid volume raised against gravity upon variation of the plate separation.
From: Rough capillary rise
Predicted volumes from the Dual-Rise model are compared for the simulated, square-pillared system SQ2 with water as the rising liquid (capillary length λc = 2.7 mm) and θ = 58°. The total volume VT is shown, which is decomposed into the individual contributions from: capillary rise VC, hemiwicking VH, and the meniscus VM. The ± 1 post error bars are shown, and the plate separation d is shown relative to the roughness depth δ. Also shown are the capillary volumes calculated using: Jurin’s Law VJ, the Wenzel approximation VW, and the Cassie-Baxter approximation VCB. The three regimes of equilibrium rise are demarked and labelled 1–3.
