Abstract

The effect of wall leakage on the traditional duct flow equations based of the balance of mass, momentum and mechanical energy applied on a duct section is considered. Application of the momentum balance produces a Bernoulli equation type form, where the multiplier 1/2 in the dynamic pressure is however replaced by the value 1. Some relevant literature references are discussed. As an application, a nozzle duct flow problem is treated.
