We look at the drying process in a simple glass channel with dominant capillary effects as is the case in microfluidics. We find drying kinetics commonly observed for confined geometry, namely a constant period followed by a falling rate period. From visualization of the air/water interface with high resolution, we observe that the drying rate decreases without a drying front progression althou...

Understanding the effects of in-situ drying–wetting pattern on stress-dependent water retention curve intact loess is vital for addressing geotechnical problems in regions. The principal objective this study to investigate influence behavior loess. To meet objective, six tests were carried out using a suction- and stress-controlled pressure plate extractor. Intact was sampled from three differe...

8 A controlled-release formulation (CRF) has been developed for metolachlor, which reduced its 9 leaching in a sandy soil and improved weed control in comparison with the commercial formula10 tion. The current study tested the effect of soil wetting and drying cycles (WDCs) on metolachlor 11 fate (desorption, leaching, and weed control) applied as the CRF and as the commercial formula12 tion. M...

The objectives of this study were to determine the effects of drying and wetting (DW) cycles on soil organic carbon (SOC) mineralisation and on the priming effect (PE) induced by the addition of (13)C-labelled wheat straw to long-term no-tillage (NT) and conventional-tillage (CT) soils. We observed that the SOC mineralisation rate in rewetted soils was greater than that in soils that were kept ...

ÐA numerical algorithm is presented for the solution of geometrically challenging two-dimensional river and estuary ̄ows, based on an adaptive triangular tessellation of the ̄ow domains of interest. The governing, shallow water, equations are discretised using a ®nite volume approach embodying variable step time integrators, to yield a method that is second order accurate in both space and time...

Wetting and drying of a rigid substrate by a Lennard-Jones fluid in molecular dynamics simulations is reported. The size of the substrate particles, being smaller than the fluid particles in former simulations, is now taken to be equal to, respectively larger than, that of the fluid particles. Recently, for the latter type of system a first order drying transition has been reported. Like before...
