Краткое описание
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.
