  • Stirring method
    Patent number: 4310253
    Abstract: A stirring method comprising placing particles of a magnetic material or particles of a magnetic material coated or covered with a non-magnetic material in an interface between two phases or in a specific layer, and subjecting said particles to influences of a rotating magnetic field to cause rotation and revolution in the particles. According to this method, transfer of substances and/or heat in the interface between the two phases or in the specific layer is promoted. Also disclosed is a stir method comprising placing particles of a magnetic material or particles of a magnetic material coated or covered with a non-magnetic material in a fluid under influences of a rotating magnetic field, to cause rotation and revolution in the particles in the fluid. According to this method, transfer of substances and/or heat in the interface between a phase of the particles and a phase of the fluid is promoted.
