A Criterion for Non-Darcy Flow in Porous Media

  title={A Criterion for Non-Darcy Flow in Porous Media},
  author={Zhengwen Zeng and R. D. Grigg},
Non-Darcy behavior is important for describing fluid flow in porous media in situations where high velocity occurs. A criterion to identify the beginning of non-Darcy flow is needed. Two types of criteria, the Reynolds number and the Forchheimer number, have been used in the past for identifying the beginning of non-Darcy flow. Because each of these criteria has different versions of definitions, consistent results cannot be achieved. Based on a review of previous work, the Forchheimer number… CONTINUE READING
