directly calculated. Euler's equations are linearized about the mean flow of the airfoil or …

A domain decomposition method for the exterior Helmholtz problem

RF Susan-Resiga, HM Atassi - Journal of computational physics, 1998 - Elsevier
A new domain decomposition method is presented for the exterior Helmholtz problem. The
nonlocal Dirichlet-to-Neumann (DtN) map is used as a nonreflecting condition on the outer …

A new domain decomposition approach for the gust response problem

J Scott, H Atassi, R Susan-Resiga - 41st Aerospace Sciences Meeting …, 2003 - arc.aiaa.org
A domain decomposition method is developed for solving the aerodynamic/aeroacoustic
problem of an airfoil in a vortical gust. The computational domain is divided into inner and …

A Laplace transform/potential-theoretic method for acoustic propagation in subsonic flows

SI Hariharan, S Sawyer, DD Quinn - Journal of Computational Physics, 2003 - Elsevier
