Accelerating the Evolution of Turbochargers via Numerical Optimization and Advanced Simulation Techniques

Turbocharging the automotive internal-combustion engine has become highly topical with the trend to downsize engine capacity toward lower emissions without compromising the driver’s perception of performance and transient response. This webcast illustrates the implementation of a design-by-analysis approach in a modern, fully integrated design environment, illustrated by examples of compressor and turbine designs for small gasoline engines. Automated, numerical optimization is an emerging technology that can be deployed within such a system on several levels to eliminate much of the manual iteration, and its usefulness and implementation are described. Also, illustrations of higher-fidelity simulation are included, and their role in the design process explained. In addition, future prospects are discussed. To what extent can an empirical background in turbomachinery design become redundant in the designs of new machines? What are the major technical challenges for the developers of advanced design and analysis techniques?
