FURBISH (DAVID JON) - ARTICLE DE PERIODIQUE - 1998A numerical method based on the modified method of characteristics is developed for incompressible Darcy flow. Fluid elements modeled as grid cells are mapped back in time to their twisted forms and a strict equality of volumes is imposed between the two. These relations are then cast in terms of...Ressource payante — PermalienFonds documentaire OIEauContributeur (s):

BYRD (TRACY C.) / CUDNEY (JOSEPH J.) / FURBISH (DAVID JON) / HANDEL (ROBERT W.) / THORNE (STEPHEN D.) / WARBURTON (JEFF) - ARTICLE DE PERIODIQUE - 1998In a phreatic aquifer, fresh water is withdrawn by pumping from a recovery well. As is the case here, the interfacial surface (air/water) is typically assumed to be a sharp boundary between the regions occupied by each fluid. The pumping efficiency depends on the method by which the fluid is...Ressource payante — PermalienFonds documentaire OIEauContributeur (s):
