A MATLAB solver for Bloch analysis of a channel flow over a lattice of subsurface phonons
Abstract
This repository contains a spectral-FEM solver that computes the Bloch modes and stability characteristics (wavenumbers) of a channel flow interacting with periodic phononic subsurfaces (PSubs). It solves the generalized Orr-Sommerfeld equation coupled with a solid mechanics model for the surface admittance.
