Virtual design of efficient twin-screw superchargers for sustainable power management in engines

The concept of sustainability has gained increased importance in recent years as the planet's living systems have declined and many of its vital resources depleted. Vehicle design is changing to reflect this paradigm shift, and motor vehicles are required to meet severe requirements for fuel consumption and exhaust gas. To meet these requirements, motor engines equipped with superchargers are being introduced to the market. In this study, a CFD approach to predict the leakage flow in twin-screw superchargers is described. It allows creating an integrated CAD/CFD design environment, which can address aspects of fluid and geometry requirements for the future designs.
