Characteristic decomposition methods for the multidimensional euler equations
H. Deconinek,Ch. Hirsch,J. Peuteman +2 more
- 01 Jan 1986
TL;DR: In this article, an algebraically simple decomposition of the Euler equations for two-dimensional flows has been presented, which makes ise of two acoustic waves with orientation depending on the local strain rate tensor, and one entropy and shear wave with orientation parallel to the local pressure gradient.

Three Dimensional Flow in a Linear Compressor Cascade at Design Conditions
S. Kang,Ch. Hirsch +1 more
- 03 Jun 1991
TL;DR: In this paper, the authors measured upstream, inside and downstream of a large scale linear compressor cascade with NACA 65-1810 blade profile and found that the flow is surveyed at 15 traverse planes with 14 (in half span) × 24 (in pitch) points inside a passage, and 14 × 33 points downstream exit plane.
Convection algorithms based on a diagonalization procedure for the multidimensional Euler equations
Ch. Hirsch,C. Lacor,Herman Deconinck +2 more
- 09 Jun 1987
TL;DR: In this paper, the authors proposed a wave front propagation model for the multidimensional Euler equations, which is based on characteristic propagation properties, with the aim of following closely the physical transfer of information.

Throughflow model for design and analysis integrated in a three-dimensional Navier-Stokes solver:
A Sturmayr,Ch. Hirsch +1 more
- 01 Jun 1999
TL;DR: In this article, a multiblock multigrid Navier-Stokes solver is extended to include a throughflow model for the design and analysis of turbomachines, and the presence of the blades in the inviscid axisymmetric flow is modeled in the classical way through a distributed blade force to produce the desired turning, a blockage factor that accounts for the reduced area due to blade thickness, and a distributed frictional force representing the entropy increase due to viscous stresses and heat conduction.
