The invention discloses an electromagnetic groove composite resistance reduction device which comprises partition plates, cover plates, magnetic pole sets, magnetic pole bases and electrodes, the electrodes and the magnetic pole sets are arranged alternately, the partition plates are installed between the electrodes and the magnetic poles, the magnetic pole sets are located between the cover plates and the magnetic pole bases, and it is effectively guaranteed that the magnetic poles do not make contact with the external environment; a magnetic pole is prevented from contacting electrolyte solution and forming an electrolytic tank under the action of an electric field; the upper surfaces of the electrode, the cover plate and the partition plate are consistent in appearance, and grooves which are in approximate sinusoidal variation are formed in the arrangement direction and are divided into platform areas and slope areas; the arrangement mode of the magnetic poles and the electrodes is N + S-, every two pairs of electromagnets form one group, N represents that the magnetic pole on the upper surface of the magnetic pole group is N pole, and + represents that the power supply connected with the electrodes is positive. According to the device, electromagnetic force parallel to the upper surface of the device can be formed, and when the flowing direction of a flow field is in the direction of a groove formed in the upper surface of the device, maximum resistance reduction can be achieved.
本发明公开了一种电磁沟槽复合减阻装置,包括隔板、盖板、磁极组、磁极底座、电极,电极与磁极组交替排列,同时电极与磁极中间安装有隔板,磁极组位于盖板与磁极底座中间,有效保证了磁极与外界环境不接触,避免磁极接触电解质溶液并在电场作用下形成电解池;电极、盖板以及隔板的上表面外形一致,在其排列方向上形成近似正弦变化的沟槽,分为平台区与斜坡区;磁极与电极的排列方式为N+S‑,每两对电磁极为一组,N表示磁极组上表面磁极为N极,+则表示电极所接电源为正。本装置可形成平行于装置上表面的电磁力,同时当流场的流动方向顺着装置上表面所形成的沟槽方向时,可以实现最大化减阻。
