A preliminary design optimization approach of axial flow compressors is developed. Loss correlations associated with airfoil geometry are introduced to relax the stringent requirement for the designer to prescribe the stage efficiency. In face of the preliminary design complexity resulted from the large ...

Finally, the design results are all checked by numerical simulations due to the lack of reliable experimental data. Research has found that in order to meet the de Haller stall criterion, axial compressors require a considerable number of stages, which introduces many additional problems. Thus, a...

Applying these changes on axial flow compressors enhances individual and free access to each ...
COMPRESSORSAIRPLANE motorsAn approach for preliminary aero-engine design, incorporating a mean-line code for the design of axial-flow, multi-stage compressors, is presented. The compressor mean-line code is developed and integrated within a framework for the preliminary design and assessment of aero-...

Turbomachinery flow fields are inherently unsteady and complex which makes the related CFD analyses computationally intensive. Physically based preliminary design tools are desirable for parametric studies early in the design stage, and to provide deep physical insight and a good starting point for the ...
This paper presents structure and capabilities of new integrated environment for axial and radial turbines and compressors preliminary design. The environment makes possible to find number of different designs with inverse task solver, basing on initially specified boundary conditions, closing conditions and...
A significant result obtained from this analysis is the fact that the mass flow rate at the choking point reduces rapidly as the speed of rotation increases.Resat KuremProceedings of the 1996 Engineering Systems Design and Analysis Conference: The Third Biennial Joint Conference on Engineering ...
A theoretical study is made of the conditions for existence of the three-dimensional, or partial-span patterns of rotating stall of the axial flow compressor within the framework of small perturbation theory. Two specific problems are considered. For the infinite two-dimensional cascade, it is ...
