iv. Laminar ow reactor: A tubular ow reactor, in which the uid ow is laminar,
represents gross deviation from the plug ow assumed in an ideal PFR. Laminar
ow is a streamlined ow of uid (see Figure 3.42) in which the uid elements mix
neither in the radial direction nor in the axial direction. Whereas in an ideal PFR,
there is complete mixing of uid in the radial direction and no mixing of uid in
the axial direction.

Non-ideality in a homogeneous reactor refers to any kind of deviation from the uid mix-
ing pattern dened for ...
