- •
An impinging hot jet at high Reynolds number and small nozzle-to-plate distance is studied.
- •
Mean and fluctuating fields of both velocity and temperature are experimentally characterized.
- •
The Nusselt number and effectiveness distribution on the impinged plate are described.
- •
Primary structure dynamic is highlighted through a vortex identification and a spectral analysis.
- •
Link between the vortical dynamic and the non-monotonic Nusselt number distribution is discussed.
