LEBUの二次元チャネル流への影響に関する実験的研究

抄録

Experimental study on the effect of LEBU device was made for a two-dimensional turbulent channel flow. The local wall shear stress, mean velocity and turbulent intensity profiles were measured at the downstream positions of LEBU device located at the center of the channel width. The wall shear stress measured by sublayer plate is reduced due to LEBU device by about 10% and the logarithmic mean velocity seemes to be shifted upward to the standard profile for drag reduction case.
