- Description
- This paper reports hot-wire measurements in a turbulent sheared mixing layer (SML) generated using a composite grid, with the aim to investigate the downstream development of turbulence in the presence of a mean shear. The Reynolds number based on the mixing layer thickness δ(=y0.95−y0.10) is in the range of 6560 ≤ Reδ(=Usδ/ν)≤ 12540, where Us is the velocity difference between the high and low speeds. The measurements show that the mixing layer thickness δ grows linearly with x. The mean velocity profiles (U) collapse relatively well at all stations when the distance y is normalised by the variable η(=(y−y0.50)/δ). Further, the Reynolds stress profiles at x/M₁=60 and 65 collapse well suggesting that the decaying turbulent in the SML has reached self-preservation.
