The Vista
TF code is a streamline curvature throughflow program for the analysis of any
type of turbomachine, but has been developed in the first instance primarily as
a tool for radial turbomachinery analysis and design, such as centrifugal
compressors and radial turbines in turbochargers. Development was started in
January 2005 and the code has since become a standard tool for radial
turbomachinery design within PCA and several of their clients. An explanation
of the theory of the code and its special new features related to spanwise
mixing, and its use for choked blade rows, can be found in the IGTI paper
published earlier this year:

An
additional paper at the same conference describes its use together with a
parameterised geometry description for radial compressor design and
optimisation:

The code
development of Version 2.2, with all the features needed for radial
turbomachinery, and many features that can be used for multistage axial
turbomachinery, has now frozen for incorporation in the upcoming ANSYS 12.0
release where it will provide a capability for a through-flow (S2) calculation
for rapid evaluation of the design of radial blade rows (pumps, compressors and
turbines) at the early stages of the design optimisation. Further development
is now ongoing to incorporate treatment of real gas version which will be
issued as version 3.0 during 2009.
The Vista range of turbomachinery software includes 1D design and off-design performance codes for axial turbines, radial turbines, axial compressors, centrifugal compressors, and centrifugal pumps and additional throughflow codes for axial turbines and compressors (SC90T and SC90C).
