Buckling of scroll waves.

A scroll wave in a sufficiently thin layer of an excitable medium with negative filament tension can be stable nevertheless due to filament rigidity. Above a certain critical thickness of the medium, such a scroll wave will have a tendency to deform into a buckled, precessing state. Experimentally this will be seen as meandering of the spiral wave on the surface, the amplitude of which grows wi...

Scroll Compressor Analytical Model

The efficiency of the scroll compressor which employs the axial and the radial sealing techniques is competitive with that of the other rotary and the reciprocating compressors. The bearing load and the torque are smooth so that quiet operation is realized. 'l'herefore the machine is suitable particularly for air conditioning application. The authors have studied the scroll compressor which uti...
