Abstract: In this paper we develop a novel ray solver for the time-harmonic linearized Euler equations used to predict high-frequency flow–acoustic interaction effects from point sources in subsonic mean jet flows. The solver incorporates solutions to… read more here.

Abstract: The present study performs numerical simulations of grid-generated isotropic turbulence impinging on a symmetric airfoil at different angles of attack by utilizing the lattice Boltzmann solver PowerFLOW. The grid was chosen to match that from… read more here.
