The radial inflow turbine is the core component of the organic Rankine cycle (ORC) system.
Based on the internal flow field of the turbine analyzed by computational fluid dynamics …

New generation of spark ignition (SI) engines are expected to represent most of the future
market share in a context of powertrain hybridization. Nevertheless, the current technology …

This paper investigates performance and loss mechanism of a nozzled twin-entry mix-flow
turbine at different admissions. Two sets of partial admissions and unequal admissions are …

Automotive turbochargers operate over a wide range and require high efficiencies and
pressure ratios. These conflicting requirements and a myriad of design parameters render …

Pulsating flow in automotive turbocharger turbines makes it necessary to know performance
characteristics in difficult to measure off-design conditions. Physically based extrapolation …

A well-matched relationship between the compressor and turbine plays an important role in
improving turbocharger and engine performance. However, in the matching of turbocharger …

The structural fracture of the compressor blade is the main cause of fatigue failure. The
novelty of this paper is the creative application of bent swept-back modeling to the blade of …

Increased scrutiny on aviation's environmental footprint has precipitated a dramatic increase
in gas turbine technology development, with a focus on engine performance improvements …

The characterization of tip leakage flow plays an important role for one-dimensional loss
modeling and design in radial turbine research. Tip leakage losses can be expressed as …

This paper presents the modeling theory and results of an innovative thermal energy storage
(TES) facility, ideated, realized, and tested by ENEA (Italy). This prototype enabled the …
