Evaluation of a displacement-body model for hypersonic shock-wave/boundary-layer interaction
… a displacement-body model for strong-interaction shock-wave/boundary-layer interaction (SBLI) is presented and evaluated. The model considers 2-D flow over a flat plate with an adiabatic wall. The separation bubble is modeled as a displacement body with constant surface pressure, the value of …

Instability of steady and quasi-steady detonations
… formulation of the reactive Euler equations in a shock-fitted reference frame is derived. The formulation is specialized to three configurations: planar one-dimensional detonation, radially symmetric one-dimensional detonation, and two-dimensional detonation in a rectangular channel. High-order …

Optimization Techniques Exploiting Problem Structure: Applications to Aerodynamic Design
… assumption can be troublesome in the presence of shock discontinuities. Special treatment has to be considered for such problems and we study several approaches. Our all-at-once methods are based on the Sequential Quadratic Programming method, and are designed to exploit the structure inherent in …

Selected optimization procedures for CFD-based shape design involving shock waves or computational noise
… focuses in the transonic flow regime where shock waves may have an adverse effect on the convergence of the optimization process. In particular, the interaction of the flow discontinuity with the discrete representation of the design problem may cause the objective function to be non-smooth. …
