Entrance region. Entry region

A section of flow in a pipe over which the field of the fundamental variable quantity (velocity, temperature or concentration) depends on the conditions at the entrance and over which the boundary layer increases until it fills the entire cross section of the pipe.
Comment. Depending on the nature of the transfer process, we distinguish between a "hydrodynamic entrance region", a "thermal entrance region" and a "diffusional entrance region."
