WebSupporting: 1, Mentioning: 7 - The permeability of a saturated porous medium is an important parameter in the field of water resources and geotechnical engineering. The geometric characteristics of a porous medium are key factors in the prediction of its permeability. In this paper, particles of different shapes are constructed by Cellular … WebFracture permeability from 1 × 10 − 10 to 7 × 10 − 10 m 2 can decrease the production temperature at termination from 376.49 K to 352.93 K. This is because the fluid flow velocity increases with the increasing of fracture permeability, and the heat transfer time is greatly reduced. Sign in to download full-size image.
