Maintenance or repair of water mains may require the interruption of flow. Re-initiation of flow may present opportunities for the interaction of air and the accelerating water, resulting in undesirable pressure transients. This study focuses on air intrusion during flow startup in an initially filled horizontal pipeline supplied by a constant-head reservoir. Flow was initiated by opening the d...

a key parameter for the application of polymer gels in water shut off treatment is the adsorption of polymer gel onto the rock surface. so, the adsorption properties of a nanocomposite hydrogel were discussed in this research by crosslinking of sulfonated polyacrylamide/sodium montmorillonite aqueous solutions with chromium triacetate. the x-ray diffraction patterns indicated that exfoliated ty...

Quantum state engineering and quantum computation rely on procedures that, up to some fidelity, prepare a quantum object in a pure state. If the object is initially in a statistical mixture, then this increases the largest eigenvalue of its probability spectrum. We refer to this as probabilistic information erasure. Such processes are said to occur within Landauer’s framework if they rely on an...

Regarding the importance of interaction effect in dynamic behavior a concrete dam and reservoir, process hydrodynamic wave propagation reservoir its effects on response gravity are examined this article by presenting new probabilistic model. For purpose, program has been written an APDL environment Ansys software capable analysis system models. The Monte Carlo method with LHS applied for model,...

Reservoir modeling is the process of generating numerical representations of reservoir conditions and properties on the basis of geological, geophysical, and engineering data measured on the Earth’s surface or in depth at a limited number of borehole locations. Therefore, reservoir modeling requires an incorporation of the data from a variety of sources, along with an integration of knowledge a...
