Abstract

The hydraulic behavior of ski jumps is investigated numerically using the OpenFOAM digital library. A number of ski-jump cases has been simulated by following the RANS approach (Reynolds Averaged Navier-Stokes equations), using the k-ω SST closure model, and the VoF technique (Volume of Fluid) for the tracking of the free surface. Particular attention is given to the pressure distributions in the zone of impact of the falling jet, and to the length of the jet itself, as defined as the distance along the x-direction between the point of maximum dynamic pressure head, and the origin of the reference frame. A chart is proposed reporting the correlation line (and correspondent formal expression) between the approach Froude numbers and the lengths of the jets, in the limit of other parameters tested. The chart may serve as a useful tool for the determination of the length of the jet taking off from the bucket, starting from the value of the approach Froude number.
