Flow of Real Fluids

A survey is presented of recent advances in fundamental research into numerically modelling and experimentally observing and controlling various processes of interest in fluid mehanics. Studies on the effects of the compressibility of a flow on sound propagation are reported, including work with the reverse flow theorem for transonic flow and sound generation by airfoil-vortex interaction. Sound radiation from planes and cylinders into fluids and from turbomachinery and propellers is examined. Wave momentum and power balance in a boundary layer are investigated, along with the gas dynamics, heat, adiabatic phase transitions and wavesplitting in fluids with high specific heat. Consideration is also given to acoustic turbulence, models for slender vortex breakdown, and the vortical structure of bounded turbulent shear flow.
