Abstract
An experimental investigation of impinging 2d planar air jet on a water surface is
performed by means of Particle Image Velocimetry (PIV). The difficulty
encountered to measure the two dimensional velocity and turbulence fields close
to the interface requires a special treatment of the PIV data obtained in the air
and water sides. The resulting technique enables the localisation of the moving
interface, the use of the inter-correlation and the calculation of statistics in both
phases. The results show that the proposed PIV interface detection technique is
in good agreement with the LeDaR detection technique developed at the von
Karman Institute. The analysis of the air and water velocity field close to the
interface highlights the topological differences between dimpling and incipient
splashing configurations. The results obtained in this study will serve to model
later turbulence transfer in impinging jet configuration.
Keywords: turbulence, 2d impinging jet, interface, PIV – LeDaR.
