TL;DR: In this article, the surge phenomenon in small centrifugal compressors used for turbocharging internal combustion engines is analyzed, based on the introduction of a fluid inertia term that accounts for the non quasi steady effects and the use of a compressor map extended to the surge and negative flows zone.

TL;DR: In this paper, an analytical study of two-stage turbocharging configuration performance is presented to understand the influence of different two stage-architecture parameters to optimize the use of exhaust manifold gases energy and to aid decision making process.

TL;DR: In this article, a low pressure EGR loop was used on a spark ignition (SI) Gasoline Turbocharged Direct Injection (GTDI) engine to improve the understanding on the advantages and disadvantages of this strategy.

TL;DR: In this article, the effect of pulsating flow is investigated by means of a steady gas-stand that has been modified to produce engine-like pulsing flow, and it is shown that pulsating flows in the 40-67 Hz range (corresponding to characteristic pulsation when boosting an internal combustion engine) increases surge margin.

TL;DR: In this paper, a filtration model for wall-flow particulate filters based on the theory of packed beds of spherical particles is presented to diagnose the combined response of filter efficiency and pressure drop from reliable computation of the flow field and the porous media properties.
