Abstract
In this paper an optimization system for hydraulic machinery bladings is presented. In a first step a block-structured 3D-Navier Stokes Code has been developed. To speed up the calculation and to reach real-time behavior the computational domain may be split into several subdomains being organized by the Message Passing Interface (MPI) Software. In a second step the Real-Time Design System (RTDS) has been developed consisting of a geometrical design tool and a CFD code for fastly computing the flow. The implemented quasi-3D Euler Code has been replaced by the 3D Navier-Stokes Code. For the further optimization of the blading many different variants of the preoptimized design need to be analyzed. Since this procedure takes a lot of time an optimization tool has been developed. Thus the optimization task is performed automatically by the application of optimization algorithms. The tool can furthermore be used for inverse design. The results of a numerical optimization of a Francis turbine runner is presented. Furthermore, the inverse design is shown on a 2D blading.
