SWIFT is a multi-block computational fluid dynamics (CFD)
analysis code for turbomachinery. It solves the Navier-Stokes equations using explicit
finite-difference techniques. It can be used for linear cascades, isolated
blade rows, or multistage machines. Three differencing schemes are available –
central differences, the AUSM+ scheme, and the H-CUSP scheme. Three turbulence
models are also available – the Baldwin-Lomax, Cebeci-Smith, and Wilcox 2006 k-omega
Six test cases are included with SWIFT: Goldman's turbine
vane, the SSME two stage fuel turbine, the large, low-speed centrifugal
compressor, and NASA compressor rotors 37, 67, and stage 35. Excel files
compare computed results to experimental data.
Grids must be generated with TCGRID, available separately. SWIFT
requires a Fortran 90 compiler and PLOT3D-compatible CFD visualization
software. It is usually run on Linux systems, but can be run on a PC or Mac.
