Abstract: Smallscale turbomachines in domestic heat pumps reach high efficiency and provide oilfree solutions, which improve heatexchanger performance and offer major advantages in the design of advanced thermodynamic cycles. An ...

Abstract: Although gaslubricated herringbone grooved journal bearings (HGJB) are known for high rotordynamic stability thresholds, small clearance to diameter ratios are required for stable rotor operation. Tight clearances not only ...
