The main driver for small scale turbomachinery in domestic heat pumps is the potential for
reaching higher efficiencies than volumetric compressors currently used and the potential for …

A multi-objective, multi-period model for optimizing the design and operating strategy of
district energy systems is proposed by authors [1]. In the developed model the process and …

The design of an oil free turbocharger supported on herringbone grooved gas bearing was
formulated as a multi-objective problem, which was solved by coupling a reduced order …

The presence of oil in domestic heat pumps is an obstacle toward higher efficiency,
particularly for enhanced surface evaporators and for advanced concepts based on two …

The trend in compressors for fuel cells, heat pumps, aerospace, and automotive heating,
ventilation, and air-conditioning systems is toward ultracompact size and high efficiency …

A tolerancing method highlighting trade-offs against key design variables of mechanical
systems is proposed and applied to herringbone-grooved gas journal bearings. Gas …

High-speed turbomachinery is commonly designed to achieve high power densities. Limited
space for active cooling results in a challenging thermal management. A thermal modeling …

This paper presents the experimental investigation of a concept of Thermally Driven Heat
Pump (TDHP), based on the coupling of a vapor compression heat pump cycle and an …

Waste heat recovery (WHR) is expected to contribute to reducing CO2 emissions from
trucks. Organic Rankine cycle (ORC) systems show the highest potential for this application …
