A stability analysis is presented for staggered schemes for the governing equations of Compressible flow. The
method is based on Fourier analysis. The approximate nature of pressure-correction solution methods is taken into
account. 2001 IMACS. Published by Elsevier Science B.V. All rights reserved
These Simulink blocks contain transfer functions that model the pressure and flow transients for axisymmetric 2D viscous flow of a Compressible fluid in a straight rigid circular cross section pipelines. Three models are available:
(1) pressures at the ends
(2) flow rates at the ends
(3) pressure at one end and flow rate at the other
Filtering is incorporated to reduce numerical oscillation (Gibbs phenomenon). See J. Dyn. Systems, Meas. & Control vol 122 (2000) pp. 153-162.
