Experimental Investigation on Vibration Control of Rotor-bearing System with Active Magnetic Exciter
vibration control rotor-bearing system active magnetic exciter
2011/8/5
Vibration control is an efficient way to minimize a rotating machine’s vibration level so that its vibration fault-free can be realized. While，several factors, such as unbalance, misalignment and inst...
Magnetohydrodynamic flow in a channel with varying viscosity under transverse magnetic field
Variable viscosity electrically conducting fluid
2010/9/26
Flow of a viscous, incompressible, electrically conducting fluid with varying viscosity through a channel in the presence of a transverse magnetic field is studied in this paper. In the special case i...
