Current Research

Optimization of Supersonic Jet Noise using a RANS Approach

The objective of this SBIR Phase 1 project has been the demonstration of the feasibility of using a discrete adjoint approach coupled to a steady-state RANS-based CFD methodology and acoustic source term formulation for aeroacoustic optimization of supersonic nozzles.  The exact discrete adjoint for a coupled RANS-acoustic source term derived from the formulation used in a NASA aeroacoustic code has been implemented and verified. The sensitivities obtained using this adjoint formulation are being used to drive an aerodynamically constrained acoustic optimization of a realistic chevron nozzle configuration.

Modular High-order Unstructured Discontinuous Galerkin

A fully modular, and flexible high-order unstructured discontinuous Galerkin (DG) code is being designed and developed for general research purpose in the Aerothermodynamics branch at NASA under the supervision of Alireza Mazaheri. The objective is to develop a parallel, fully tested, dimension independent, high-order DG code that may be used for studying wide range of partial differential equations, using linear and non-linear simplex elements for continuous and/or discontinuous solutions.
