Abstract

Numerical experiments of plane jets are performed to investigate their behaviour into a still ambient and into a flow field of regular waves. SPH simulations are obtained by a pseudocompressible XSPH scheme with pressure smoothing; turbulent stresses are represented by a two-equation k-ε model. The SPH model is validated by comparing the obtained results with experimental measurements and analytical solutions. The main fluid mechanical characteristics of jets discharged either in still water or transversally to regular wave trains characterized by different heights are compared. The study focuses specifically on the role played by the wave heights on the velocity distribution.
