Abstract
A study was made on electrically conducting flow over a flat plate boundary layer controlled with streamwise stationary Lorentz forces. Two different velocity measurement methods were used for the experimental investigation: laser Doppler velocity profile sensor and time resolved particle image velocimetry. The flow measurements were mainly focused on the near-wall behaviors of the flow with different magnitudes of the Lorentz forces. Velocity distributions and local acceleration were evaluated from the experiments. The experimental results revealed that the near-wall fluid is accelerated due to the streamwise Lorentz force and the turbulence fluctuation is suppressed by the increase of the Lorentz force applied. The limitations of the experiments and the future perspectives on the investigation are addressed.
