Evaluation of a Higher-Order Immersed Boundary Method for Viscous Flows and Fluid Structure Interaction


Project Description:
In the first part of the project, new wall modeling approaches (or viscous wall extensions) coupled with an IBM are being evaluated to account for the viscous boundary layer interacting with the solution away from solid walls. In contrast to common wall modeling approaches that usually only utilize local flow information, the pursued method keeps the history of the boundary layer. This is why this method is effective at much larger y+ values than local wall modeling approaches. After analyzing these methods theoretically, they are applied to increasingly more challenging flow fields including fully attached, separated, and shock-induced separated (laminar and turbulent) flows.


In the second part of the project, the immersed boundary method (IBM) by Brehm et al. (2013, 2015) is evaluated for moving boundary and fluid-structure interaction problems. The novelty of this approach is to employ locally stabilized higher-order accurate finite-difference stencils. The key advantage of IBMs is that the computational meshes can automatically be generated starting from a watertight surface triangulation independent of the complexity of the geometry. Moreover, for flows containing moving boundaries, IBMs facilitate the numerical solution procedure by solving the governing equations on a stationary, non-deforming Cartesian grid. In contrast, conventional body-fitted grid approaches are confronted with immense difficulties in the solution procedure, especially for fluid-structure problems with large boundary displacements.

Prediction of Boundary Layer Transition on Hypersonic Vehicles in Large Scale Wind Tunnels and Flight


Project Description:
In this project, we develop algorithms to predict the onset of strongly second mode dominated boundary layer transition in large-scale hypersonic wind tunnels (Marineau 2015) and include relevant physics to allow extrapolation to flight. Several direct numerical simulations of hypersonic boundary layer flows are conducted to obtain a better understanding of the transition process. The transition prediction tools are verified against conventional stability solvers, results from direct numerical simulations, and available experimental data
