چکیده
Presently the on-the-road transportation sector is responsible of 21% whole CO 2 amount emitted into atmosphere. This pushes International Governments and Organizations to provide strict limitations in terms ICEs emissions, also introducing fees payment for car manufacturers. The vehicle electrification allows certainly meet these requirements, but higher cost need a green electricity still limit widespread diffusion among all social classes. Thus, technological improvement internal combustion engine plays key role transition period. Among technologies, thermal management achieve good compromise between emission reduction related costs. It was demonstrated that replacing conventional centrifugal pump cooling system with sliding vane rotary (SVRP), important benefits can be achieved as efficiency decreases significantly when works far from maximum load (i.e. design point pump). Nevertheless, complex thermo-fluid-dynamic phenomena taking place inside SVRP make its not immediate, particularly if heavy duty ICE systems are considered. These applications indeed challenging due wide operating range huge flow rates which must deliver. requirements difficult choice main parameters: different ones, revolution speed displaced volume. In present paper strategy developed this type pumps based on comprehensive mathematical model processes occurring, predicting volumetric, indicated mechanical efficiencies. validated experimental activity so acting virtual development platform. results show how best global (0.59) adopting dual axial intake port configuration, suitable result trade-off volume speed. analysis keeps close one an ICE.

Evaluation of Composite Vane Materials for Rotary Sliding Vane Compressors
The physical performance characteristics of composite materials used for vanes in rotary, sliding-vane compressors, in general, are several orders of magnitude more difficult to quantify for design purposes than most homogeneous materials. This arises from the numerous variables that influence the response of these materials under the severe environmental conditions existing in such compressors...

This paper investigates 3D simulation of fluid flow in a centrifugal pump from the Detroit Diesel company to extract possible engine cooling trends. The velocity and pressure profile of water, the coolant, is analyzed and the characteristic curves of the pump are derived. This provides a useful evaluation of the pump performance at all working conditions. For this aim, a computational fluid dy...

On the Optimal Design of One-Rotor Two-Stages Rotary-Vane Compressors
The efficiency increase reachable with more than one compression stage is a well known result of the thermodynamic principles, since this allows the gas cooling between consecutive stages and makes the transformation approach the isothermal limit. In the sliding vane rotary compressors is possible to integrate two stages of compression within a single stator, so to keep down the system dimensio...
