Converging flow tracer tests in fissured limestone

Single Phase Flow in Partially Fissured Media

Totally ssured media in which the individual cells are isolated by the ssure system are eeectively described by double porosity models with microstructure. Such models contain the geometry of the individual cells in the medium and the ux across their interface with the ssure system which surrounds them. We extend these results to a dual-permeability model which accounts for the secondary ux ari...

Single Phase Flow in Partially Fissured Media

Totally fissured media in which the individual cells are isolated by the fissure system are effectively described by double porosity models with microstructure. Such models contain the geometry of the individual cells in the medium and the flux across their interface with the fissure system which surrounds them. We extend these results to a dual-permeability model which accounts for the seconda...

Unsteady Flow in Vertical, Converging Tubes

INTRODUCTION The discharge ofliquids from vertical tubes with various con­ traction geometries was studied via the unsteady Bernoulli equa­ tion. The temporal variations of the exit velocity and fluid level in the tube were found from the numerical integration of nonlin­ ear differential equations. Sudden, quadratic, and exponential contraction geometries were considered. For inlet to exit area...

Radial Flow Permeability Testing of Indiana Limestone

The geotechnical importance of studying fluid flow through porous media and soils in particular, becomes evident when dealing with groundwater movement in surficial geomaterials that can be initiated by hydraulic gradients that develop during construction activity, groundwater extraction, impounding of reservoirs and groundwater recharge during adverse climatic events. In a geotechnical context...
