Flow entrainment

Webapproach flow. (ii) Entrainment limit The conditions of the approach flow govern the entrainment limit and are quantified by the Froude number (see below). A critical Froude number must be exceeded for air entrainment to occur. For higher Froude numbers, the approach flow provides the driving mechanism for air entrainment. 2 WebA recent overview for multiphase flow correlations for inclined and horizontal flow in pipelines is provided in Jerez-Carrizales et al.
