Abstract
The development of the unsteady boundary layer produced from an impinging jet with a temporal puslation forms part of the complex flow physics occurring within an internal combustion engine and its characterisation is crucial for improved modelling with lower-fidelity tools. The momentum boundary layer prediction of these flows currently relies on wall-modelling based on the logarithmic law of the wall for equilibrium zero pressure gradient boundary layers. However, it is not fully understood how these non-equilibrium boundary layers evolve and whether the reliance on the law of the wall is justified for modelling such flows. Thus, in this paper, we attempt to characterise the momentum bound..
