Correlations are used by the engineer for design purposes and/or when a theoretical calculation is missing. The purpose of this paper is to show that, applying the momentum integral equation, it is possible to derive correlations for flow situations associated with a deceleration. Four different cases are presented in the paper: (a) The case of the profile losses in a cascade of blades; (b) the case of the secondary losses in a cascade of blades; (c) the case of the turbulent shear layer before reattachment in a laminar separation bubble; (d) the case of the interaction of a shock with a turbulent boundary layer. At the same time the important factors governing these flow situations are put into evidence.
