The team of Mohawk Innovative
Technology Inc., (MiTi), University of
Texas – Center for Electro-Mechanics
and MITIS of Belgium propose a truly
transformative, ultra-high-speed and oilfree,
Hyperlaminar Flow Engine (HFE)
system that combines low cost viscous
shear driven compressor and expander,
an integrated low pressure drop
recuperator, flameless combustor,
permanent magnet generator, lubricant
free air foil bearings, advanced power
electronics and thermoelectric generator
elements to meet the needs of a
residential combined heat and power
(CHP) plant with 40% electrical
efficiency, 2kW total capacity (50/50
thermal/electrical) with low NOx and
CO2 emissions (estimated at 4.1E-5
lb/MW-h, and <900 lb/MW-hr) and no
particulate matter. The proposed concept
(see Figure 1 and 2) will use the viscous
shear driven compressor and expander
discs with micro-inch scale flow patterns
and close clearance compliant foil
mating surfaces to achieve the desired
pressure and flow at very high spin speeds. While Figure 2 shows grooves and tessellation
patterns etched on discs, they may be applied to the compliant surface to greater effect. MiTi's
5th generation foil bearings use no lubricants, have very low power loss, nearly unlimited speed
and life capabilities and require no maintenance. Due to the high operating frequencies of the
machine (i.e., ~5 to 6 kHz), structure-born and airflow acoustic noise damping is readily
achieved. Thermal insulation materials will damp structure born noise. Primary noise reduction
in the exhaust airflow will be achieved using flow speed induced frequency drift noise
cancellation via appropriate recuperator and exhaust path geometries. The unique combination of
technologies, including the micro-scale flameless combustor with the viscous shear compressor
and expanders, foil bearings, PM generator, high frequency power electronics and technical
expertise of the assembled team are what make this innovative and transformative concept very
feasible. This stand-alone system concept will meet all of the efficiency, emissions, cost and
weight metrics of this FOA.
