Application of the magnetic fluid in viscosity drag reduction

Drag reduction is always a popular field in science research. The reason lies in that it has the wide applications and important academic merits. Magnetic fluid is a kind of two-phase colloid fluid which is mixed by dispersion of magnetic particles evenly into the carrier fluid. The uniform of liquidity and magnetic property in magnetic fluid produce more possibility for new applications. Magnetic fluid viscosity drag reduction is a new type of drag reduction method which has so many advantages as simple structure, excellent controllability, long life, far using range, etc. The work of this paper is focused on experiment of magnetic fluid drag reduction research.
