Abstract
The effect of a magnetic fluid cover of heat transfer and drag of a cylinder at a transversal flow of oil around it has been studied experimentally. If the cylinder surface is covered with a layer of poorly viscous magnetic fluid (the ratio of viscosity of the oil and the magnetic fluid η₁/η₂ being 7.96), the reduction of hydraulic drag will be up to 15.5
