Adjoint-based optimization for hyperbolic balance laws in the presence of discontinuities
… when the interface is represented by a Heaviside marker function. We will study the two main discontinuous wave patterns that appear in hyperbolic balance laws: contact discontinuities and shocks. These two have very different characteristics in the forward problem and we will see that they …

Quantification of Reynolds-averaged-Navier-Stokes Model Structural Hypothesis Uncertainty in Transitional Boundary Layer and Airfoil Flows
… amplitude perturbation, and we developed a novel marker function to identify the doubtful regions where uncertainties should be assessed. The uncertainty bounds for the skin friction coefficient, wall pressure coefficient, mean velocity field and Reynolds shear stress distribution have been …
