Abstract

Measurements are reported of the temperature and velocity fields above an adiabatic flat plate through which air is injected via a row of circular injection holes inclined at an angle of 35 degree to the surface. A mainstream flow of air over the plate is present, with Reynolds number based on stream velocity and injection tube diameter of 3. 4 multiplied by 10**3 throughout the experiments. The boundary layer approaching the row of holes is either laminar or turbulent and either fully-developed laminar or turbulent pipe flow is present in the injection hole (in the absence of the mainstream). The jets emanate from the holes at a mass flux rate from 0. 2 to 2. 0 times that of the mainstream flow.
