Magnetic Reynolds number

This allows one to draw two conclusions. First, the theorem of the impossibility of a dynamo with vn = 0 for arbitrary magnetic Reynolds number Rm is valid only for plane and spherical geometries. Second, the increment of a dynamo which is possible in other geometries will be determined by the magnetic diffusion and, consequently, such dynamos are effective only for small magnetic Reynolds numbers. [Pg.103]

The flow of fluids under the influence of magnetic and electric fields can be readily analyzed via classical MHD theory. In its application to aqueous electrolytes, compressibility and viscous effects may usually be neglected in the equation of motion. The magnetic Reynolds number... [Pg.346]

In this model, the current due to convective motion of the melt has been neglected, because the magnetic Reynolds number for this system is of the order of 10, which means that the charge transported by convection is much smaller than the diffusive current. The electric field intensity, E, can be used to calculate the local heat release rate in the slag or bullion by Joule heating according to the equation ... [Pg.695]

The authors then establish a plot (see Figure 5.3) in the plane (Rer, Gr), where Gr is the Grashof number and Rer is the total Reynolds number, equal to the sum of the viscous Reynolds number and a magnetic Reynolds number. Hence, we have the following definitions ... [Pg.107]
