OPTIMAL DESIGN FOR THE INTERIOR SHAPE OF A ANNULAR DIFFUSER WITH DIVERGENT CAREENING CONSIDERING THE MINIMUM WHOLE LOSS PRESSURE

摘要

In this paper is presented a new mathematical model and a numerical programme in Mapple 11 programming language, for optimum design of the interior shape of a hydraulic annular diffuser with interior divergent careening. The mathematical model was determined to respect the minimum values of the whole loss pressure. The proposed programme solves numerical the nonlinear mathematical model and prints the results.
