Abstract: A method to address the rotor/stator interaction problem on an edge-based Reynolds-averaged Navier–Stokes solver is presented. The implementation of the phase-lagged boundary conditions and a new original conservative discretization of the sliding plane in an unstructured solver is discussed in detail. The numerical method is implicit in time, and convergence is accelerated using a multigrid technique where the coarser grids are obtained by agglomeration. Results of the present method are compared with the experimental results obtained at the National Aerospace Laboratory (The Netherlands) for a subsonic fan.

Nonlinear Dynamics of Bladed Disks with Multiple Unstable Modes
TL;DR: In this paper, a simple model that describes the nonlinear dynamics of bladed disks due to dry friction exerted in the attachment of the rotor blades with the disk, and the unsteady aerodynamic forces induced by the vibration of aerodynamically unstable airfoils, is presented and analyzed.

Compressor surge based on a 1D-3D coupled method – Part 1: Method establishment
TL;DR: In this paper, a 1D-3D coupled method for simulating compressor surge in a compression system is presented. But, the method fails to capture highfrequency modes and a quiet zone during a surge cycle, which are respectively attributed to rough temporal and turbulent resolutions and rotational speed variations during compressor surge.

Study of a modern industrial low pressure turbine for electricity production employed in oxy-combustion cycles with CO2 capture purposes
TL;DR: In this paper, a detailed comparison of the same modern industrial low-pressure turbine, LPT (low pressure turbine), is part of a modern gas turbine used currently for electricity production and the comparison is focused on the LPT's phenomenology working with the fluid present in normal conditions and with the new fluid presented in semi-closed cycles with oxycombustion for CO2 capture.
