“…6 describes the position and the characteristics of the sampling zone for LES results. Sampling location and size is chosen to match the sampling area of the PIV data reported in Bovo et al [20]. The area is 1/3 of the distance between the simulation's inlet and the impingement surface.…”

“…The measurement campaign focused on studying the evolution of the pulse-jet impinging on a flat target at different angles with respect to the jet's axis. A detailed description of the experimental apparatus can be found in Bovo et al [20]. The time-space evolution of the jet's velocity field was measured with PIV (Particle Image Velocimetry).…”

a b s t r a c tExperimental results are commonly used to validate numerical simulations. Often, it is challenging to accurately reproduce the experimental setups in the numerical environment, thereby leaving uncertainty in the validation process. An experiment on impinging jets was designed with boundary conditions well suited for implementation in the numerical environment. In this work, LES was implemented to specifically match the experiment of a single-pulse jet impinging on a surface oriented normally to the jet axis. The experiment was designed primarily to study the thermal effects on the impingement zone with high space-time resolution. The temperature evolution of the impingement target was measured via IR camera. The space-time resolved jet velocity-field was measured with PIV and was used as boundary condition for the simulation. The focus of the LES was to replicate the experiment as faithfully as possible in the virtual environment. LES was run multiple times to allow statistical evaluation of the results, as done in the experimental procedure. High levels of agreement were found between the LES and the experimental results, both from a qualitative and a quantitative point of view. This work could therefore be considered as a successful validation of the LES in the study of this type of flows.
