Abstract

In recent years, considerable efforts have been devoted to improving the performance of radial diffusers. This can be achieved by obtaining a p < /strong>roper diffuser design. 
The analysis followed in this paper is based upon solving the momentum equation of incompressible turbulent boundary layer under certain assumptions. It is possible to p < /strong>resent the velocity profile parameters as dep < /strong>endent upon definite numbers, from which sep < /strong>aration could result. This helps in solving attached boundary layers with maximum deceleration. For the case in hand, the assumptions considered that the velocity profile parameter, Aopt, has a magnitude of about 0.00094, and ᵟ⃰/ᵟ⃰⃰⃰⃰⃰⃰ranges between 1,4 to 1.6, for maximum deceleration (5). 
To evaluate the mathematical model developed in this work, its results will be compared with previous available experimental data. This obtained results show that the maximum deceleration is obtained by decreasing the initial value of momentum thickness at diffuser entrance.
