heal.abstract | In this diploma thesis, turbomachinery endwall shape design methods are applied in the open case of NASA Rotor 37, aiming to a performance and operability bene t. The purpose of this diploma thesis is to present solutions of the endwall shape produced by a manual iterative design process, after cross validating results computed by the PUMA CFD ow solver, developed by PCOpt/NTUA, against computational results and experimental data available from NASA literature. For compressors, the endwall regions are associated with losses, being critical regions of low momentum uid, that lead to operational restrictions. Endwall contouring was used in order to control the overturned boundary layer of the highly loaded compressor blade, reduce the ow separation which is generated in the ow at the root of the blade and mitigate the total pressure losses over the design speed. Speci cally, the endwall surfaces were perturbed near the region of the blade to create convex and concave shapes with the use of B-Splines. The endwall contours were investigated for the hub and the casing of the rotor and provided satisfying improvements to both the performance and the operability of the NASA Rotor 37 case. For the design of the endwall geometries and the discretisation of the domain, the CFD mesh generation tool PADRAM (Parametric Design and Rapid Meshing { developed by Rolls-Royce plc.) was used to mesh the di erent geometries of NASA Rotor 37, while the the GPU-enabled CFD ow solver PUMA was used for simulating the ow in the rotor blade row. A part of the work was carried out at the Rolls-Royce Plc premises in Derby. | en |
