Specialization and Research Interests
Current research involves the development of computational algorithms for the prediction of 2D and 3D external flows about aerodynamic bodies. Subsonic, transonic, and supersonic flow regimes are being considered. Most of the work centers on viscous/inviscid coupling schemes in conjunction with direct Newton solution methods. Two- and three-dimensional integral boundary layer formulations are also being developed for modeling viscous regions. Specific geometries currently being considered include high-lift multielement airfoils, wing/body configurations, and axisymetric powered engine nacelles. Research into optimization techniques and strategies is also being pursued in parallel with computational aerodynamics work. A key goal is the development of methods for efficient calculation of design-parameter sensitivities. Also being pursued is the development of interactive tools to permit the designer to make the most effective use of the computed design parameter- sensitivity information to guide the evolution of a design.
Primary research interests are in low speed and transonic aerodynamics, physical modeling and design of aircraft and aeromechanical devices, and development of computational aerodynamic design/analysis codes which are currently being used in the aircraft and gas turbine industry.
