摘要
Electromagnetic, i.e. Lorentz forces, may be used to influence the flow of electrically conducting fluids. The present paper investigates the application of time periodic Lorentz forces to the control of the suction side flow on a NACA 0015 hydrofoil. Experimental results, consisting of flow visualizations and force measurements, characterizing the control effect in the low Reynolds number range of 10(4) less than or equal to Re less than or equal to 10(5), are presented. A comparison of the forcing effect with stationary Lorentz forces on one hand and conventional oscillatory, blowing on the other hand is given as well. (C) 2004 Elsevier SAS. All rights reserved.
