 note = {The results of an experimental investigation on the effect of a spanwise oscillating Lorentz force on the near-wall turbulent structures for drag reduction are presented in this paper. Comparing with the case of turbulent control by spanwise wall oscillation, a parameter called equivalent spanwise wall velocity W(+)(sub eq) = StT(+)/(2pi Re(sub tau)), is defined and emphasized as a virtual spanwise wall velocity scale under Lorentz force oscillation. It is shown that when W(+)(sub eq) approximately equal to 10 to 15, up to 30 to 40 percent skin frictional drag reduction could be achieved just at the downstream of the control area. Meanwhile, an oscillation amplitude investigation suggests that to achieve maximum skin friction reduction, the oscillation Lorentz force should be able to shift the near-wall streamwise vortices into spanwise direction by a peak to peak displacement of about 100 wall units during each period. A conceptual model to explain the mechanism for drag reduction under the spanwise Lorentz force oscillation is also presented., 資料番号: AA0047776013, レポート番号: JAXA-SP-04-002},
