Simulation of transitional and turbulent flows

Turbulent flows are the norm in technical applications. While the statistical description of turbulence still remains the standard for simulating hydraulic flow machinery and components, increasingly scale-resolving simulations such as LES, or in exceptional cases even DNS, can be employed due to ever-greater available computing resources, often providing significantly more accurate results than statistical models.

At HSM, scale-resolving methods are used when statistical methods are not expected to provide sufficient accuracy. The focus is on the application of existing models and methods and their adaptation for use on hydraulic flow machinery and components. Due to the absence of licensing costs even under extreme parallelization, OpenFoam is primarily used.

Furthermore, fundamental investigations into the stability behavior of swirl-influenced flows in gap geometries are carried out at HSM using linear stability analyses.
