Disk-Pack Turbine

A disk-pack turbine comprising:

• two disks each having a waveform surface and a second surface, the waveform surfaces face each other and have an axially centered waveform pattern, at least one disk includes an axially centered opening passing from the second surface to the waveform surface, said disks define an expansion chamber including the at least one opening and a disk chamber between said disks from the expansion chamber to a periphery of said disks,
• said waveform pattern having at least one waveform that has an amplitude that varies in a radial direction and said waveform pattern maintains or increases a number of peaks for each level of waveforms progressing out from the inner most waveform about said axial center to said periphery where the increase is by a multiplier of 2 to 8,
• a fluid pathway runs from one of the at least one opening to said periphery of said disks through the expansion chamber into the disk chamber, this opening converges a fluid flow prior to the fluid flow expanding into the expansion chamber, and
• said second surfaces have a slight parabolic shape or are flat.
