## Chapter 6: Vista CCD

The Vista range of turbomachinery software includes 1D design and off-design performance programs for axial turbines, radial turbines, axial compressors, axial fans, centrifugal compressors, and centrifugal pumps.

The subject of this user's guide is Vista CCD. Vista CCD is a program for the preliminary design of centrifugal compressors. It can be used in an iterative fashion to create a 1D design. The resulting geometry can be passed to BladeGen or BladeEditor. Vista CCD can be used to model an existing compressor and, if known, its measured performance at single operating points. An accurate 1D model can provide insight into the performance of the machine that goes beyond the test measurements.

Vista CCD is integrated into ANSYS Workbench so that it may be used to generate an optimized 1D compressor design before moving rapidly to a full 3D geometry model and CFD analysis.

Vista CCD is provided by PCA Engineers Limited, Lincoln, England.
