Estimating mean profiles and fluxes in high-speed turbulent boundary layers using inner/outer-layer transformations

Asif Manzoor Hasan, Johan Larsson, Sergio Pirozzoli +1

Accurately predicting drag and heat transfer for compressible high-speed flows is of utmost importance for a range of engineering applications. This requires the precise knowledge…

Incorporating intrinsic compressibility effects in velocity transformations for wall-bounded turbulent flows

Asif Manzoor Hasan, Johan Larsson, Sergio Pirozzoli +1

A transformation that relates a compressible wall-bounded turbulent flow with non-uniform fluid properties to an equivalent incompressible flow with uniform fluid properties is der…

Grid-Adaptation for Wall-Modeled Large Eddy Simulation Using Unstructured High-Order Methods

Marcel Blind, Ali Berk Kahraman, Johan Larsson +1

The accuracy and computational cost of a large eddy simulation are highly dependent on the computational grid. Building optimal grids manually from a priori knowledge is not feasib…

Towards systematic grid selection in LES: iterative identification of the coarse-graining length scale by minimizing the solution sensitivity

Siavash Toosi, Johan Larsson

The accuracy of a large eddy simulation (LES) is determined by the accuracy of the model used to describe the effect of unresolved scales, the numerical errors of the resolved scal…

Toward real-time high-fidelity simulation using integral boundary layer modeling

Alexandre Marques, Qiqi Wang, Johan Larsson +2

One of the greatest challenges to using large-eddy simulations (LES) in engineering applications is the large number of grid points required near walls. To mitigate this issue, res…

Heat transfer and wall temperature effects in shock wave turbulent boundary layer interactions

Matteo Bernardini, Johan Larsson, Sergio Pirozzoli +1

Direct numerical simulations are carried out to investigate the effect of the wall temperature on the behavior of oblique shock-wave/turbulent boundary layer interactions at freest…
