A compact sized PDE with an i.d. of 0.75 in. and length of 1 m was paired with an automotive turbocharger. The turbine-compressor shaft was used to drive a small ac generator by means of speed reduction wheels. The PDE was tested with propane-oxygen mixture at 15 Hz for a period of about 20 s. The turbine spun up to a speed of 127,000 rpm, whilst the generator produced electric power at 27 W an...

In order to improve centrifugal compressor performance predictive capability, an improved recirculation loss model in two-zone modeling system is presented in this paper. The new loss model correlates Reynolds number of the impeller with the recirculation loss. Performance prediction by the improved model is carried out on two turbochargers with different sizes based on COMPAL mode of the code ...

The objective of this work regards an SOFC system pressurized by a turbocharger and the related emulation tests for control development. Due to interest in coupling high efficiency operations with reasonable capital costs turbocharged plant layout has been proposed. This is due significant cost decrease (in comparison microturbine-based hybrids) application based on large mass manufacturing pro...

MEMS turbocharger and electric generator devices have been fabricated and tested as part of a program at MIT to develop a microfabricated gas turbine generator for portable power applications. The overall efficiency of this device, relative to its conventional-scale brethren, is limited by small-scale physics and microfabrication constraints. However, even at modest efficiency levels, the perfo...
