The heat transfer along one cycle has increased in the finned compressor by 32 times compared to a classic piston compressor.
In the best case, there was a reduction of frictional power losses for the simulated piston ring assembly by 40 51% compared to a commercially available lubricant.
This machine integrates one piston and two displacers placed in a symmetrical way compared to the piston to improve the stability of the machine.
It was shown that compared to conventional piston or mixed ventilation, around 30% reduction in the ventilation flow rate may be achievable with the PRESEV strategy.
As a consequence, SCC will generate relatively higher NO compared to other two piston bowl designs at low engine speed condition.
This suggest that in this frequency range, complex footplate motion may induce higher volume velocity compared to piston footplate motion with velocity measured at the center of the footplate.
Low vibration Stirling cryocoolers often rely on dual-piston linear compressors, the known disadvantages of which, as compared to their single-piston rivals, are: low reliability, increased power consumption, price, bulk, sensitivity to external vibration and g-forces.
Compared to the traditional piston-ring sealing displacer, the sealing clearance between the ridge of the labyrinth sealing displacer and cylinder is critical to the cooling performance of the G-M refrigerator.
The near to farfield transition distance for acoustic BB fields is investigated and compared to the Rayleigh distance for a piston source.
If operated as a four-stroke cycle, the linear generator must be used as both a motor and a generator resulting in a more irregular piston motion compared to corresponding operating in a two-stroke cycle.
