Mathematical model of water drop trajectory in artificial rainfall

Subsurface Water Movement and Downslope Deformation in Model-Slope Tests by Artificial Rainfall

The flowslide is reproduced by the quasi-real scale model-slope tests on river sand by artificial rainfall, in which subsurface water movement and downslope deformation are carefully monitored. The rainfall at the intensity of 100 mm/hour on the specimen formed at loose state (9.0-metre long, 1.0-metre wide, 0.5metre deep) have brought about the failure at 2,931 sec after the onset of sprinklin...

Artificial Rainfall

In many regions of the world traditional sources and supplies of groundwater, rivers and reservoirs are either inadequate or under stress from increasing demands on water from changes in land use and growing population. The ability to influence and modify cloud microstructure in certain cloud systems has been demonstrated and verified in laboratory, modeling, and observational studies. Cloud se...

Prediction of Pressure Drop of Al2O3-Water Nanofluid in Flat Tubes Using CFD and Artificial Neural Networks

In the present study, Computational Fluid Dynamics (CFD) techniques and Artificial Neural Networks (ANN) are used to predict the pressure drop value (Δp ) of Al2O3-water nanofluid in flat tubes. Δp  is predicted taking into account five input variables: tube flattening (H), inlet volumetric flow rate (Qi  ), wall heat flux (qnw  ), nanoparticle volume fraction (Φ) and nanoparticle diameter (dp ...
