Struktura turbulencji i bilans jej energii w warstwie przyściennej na powierzchni przepuszczalnej

The effect of uniform wall suction on the mean flow characteristics and the turbulent structure of boundary layer on a permeable flat plate has been experimentally investigated. The results discussed have included the mean velocity profiles, turbulent energy and Reynolds stress distributions, time-correlations and energy-spectra in turbulent boundary iayer controlled by surface suction. The energy-exchange processes have been analysed with special attention to the contribution of the production and dissipation terms for the total turbulent kinetic energy balance.
