Three-Dimensional Numerical Study of the Magnetic Effect on the Air Flow at an Intake

Abstract

Magnets attract the air which is paramagnetic and give influences to air flows. In this study, air flows at an intake with magnetic fields are examined by means of three-dimensional numerical simulations. The flow is assumed to be compressible and inviscid. Under the magnetic fields, vortices are generated near the magnet by magnetic forces. Vortices disturb the air flow and relieve the flow congestion. The flow rate at the intake with magnets increases rapidly and it becomes almost three times as large as that without the magnetic fields.
