Natural gas storage process in aquifer, due to fluid flow behavior of gas and water in the porous medium and because of their contact with each other under reservoir conditions, faces several challenges. Therefore, there should be a clear understanding of the injected gas behavior before and after the injection into the reservoir. This research simulates the natural gas storage in aquifer by us...

After the first water channel was cloned and sequenced from 1991 to 1992, work in this field has proceeded at a rapid pace. It is clear now that many tissues in the eye have water channels, and that number could continue to grow. In all probability, water channels are the conduits for transcellular and translayer water flow in the kidney collecting duct, and their presence in water-permeable ep...

Abstract Roughness of surfaces significantly influences how methane and water flow in shale nanopores. We perform molecular dynamics simulations to investigate the influence surface roughness on pore-scale transport pure as well two-phase methane–water systems with sliding droplets over pore surface. For single-phase flow, shows a limited bulk density, while it reduces capacity. In systems, mob...

Foreword High flows of water is a common problem in most rivers. Earlier generations were more aware of the risks to build close to the rivers and the highest water level was locally known. Nowadays, building permits are more and more frequent below that level. Furthermore, forestry methods with clear cuts and drainage of wetlands result in a more rapid effect of heavy rain fall on the water fl...

hydrograph analysis is a complex problem in a variety of water resources investigations and its estimate is critical in the assessment of low flow characteristics of river for use in water supply, water management and pollution assessment. the paper describes different methods of base flow separation based recession analysis from daily river flow records and distinguishes the most suitable meth...

Ecosystems in the Caspian Sea region have been heavily modified by anthropogenic activities, mainly as a result of changes in the water flow and degradation of the water quality in the ecosystems. Changes in the regional environment have influenced regional economies, particularly obvious in the impacts on fish stocks. Using the methodology developed in the GIWA project, experts in the region c...

in this study digital image correlation (dic) technique combined with a high speed video system was used to predict movement of particles in a water model. comparing with particle-image velocimetry (piv) technique, it provides a low cost alternative approach to visualize flow fields and was successfully employed to predict the movement of particles in a water model at different submergence dept...
