概要:

application/pdf<br />Journal Article<br />The sructure of turbulence in a wall jet along a plane surface is investigated by measuring the balance of turbulence energy. With the aid of a hot-wire anemometer system, convection velocities of small-scale turbulent motion are measured as well as other time-averaged flow properties and turbulence characteristics. It is found that the convection velocity of small-scale turbulence deviates significantly from … the mean flow velocity, that is, Taylor's hypothesis is not valid for the present wall jet, and the present results on turbulence energy balance agree much better with theoretical predictions by the turbulence model than do those based on Taylor's hypothesis. 続きを見る
