Air–water flows are among the most important flow types in hydraulic engineering. Their experimental modelling at reduced size using Froude scaling laws introduces scale effects. This study introduces novel scaling laws for compressible air–water flo... Read More about Numerical validation of novel scaling laws for air–water flows including compressibility and heat transfer.

New Physical Insight into Landslide-Tsunamis Using Non-Linear Wave Decomposition (2022)
Presentation / Conference Contribution
Constance, B., & Heller, V. (2022, June). New Physical Insight into Landslide-Tsunamis Using Non-Linear Wave Decomposition. Presented at 39th IAHR World Congress, Granada, Spain

Potentially devastating tsunamis are generated by landslides impacting into water bodies. Such subaerial landslide-tsunamis are typically predicted with empirical equations, which, however, fail to appropriately capture some of the underlying physics...
