Abstract A fluid-cooled seal rotor is described for a seal assembly that includes a seal case, a seal stator, and wherein the rotor has a sealing face on a first side and a heat-transfer structure on a second side. The heat-transfer structure may be a roughened surface. The heat-transfer structure may have protrusions which may be fins, including fins with roughened surfaces. The heat-transfer structure may have additional heat-transfer structures thereon to create complex, including fractal, structures. The fins may be shaped as impellers to move oil over the heat-transfer structure. Channels between fins may have a width greater than twice the boundary layer thickness for the fluid engaged by the fins. The fluid-cooled rotor, the seal assembly having the fluid-cooled rotor, an air turbine starter having the seal assembly, air turbine starters and other machines with rotating shafts using the seal are within the scope of the invention.
