Turbochargers are expected to meet demands for high performance and maximum reliability. To meet these sometimes contradictory goals, many design aspects of the turbocharger and their interactions must be studied, including rotordynamics, friction, plus temperatures of structure and fluids, in addition to fundamental performance. In GT-SUITE, these complex scenarios can be efficiently modeled with detailed physics, including having a fast running beam approach for rotordynamics to predict shaft deflections and resonance behavior. Friction can be accounted for in common surfaces of the turbocharger including floating bushings, thrust bearings, and ball bearings. Finally, a thermal model can be built to predict heat distribution and ultimately fluid temperature inside the turbocharger in order to study temperatures of the individual parts, such as the compressor and turbine wheel, or to keep oil and any dedicated coolant below acceptable limits.
This 25-minute webinar will discuss how GT-SUITE is well suited for solving these complex problems in turbocharger modeling.
