11:15 The optimisation of airpath component
installation to maximise pressure charging
system performance
- How the vehicle package compromises the functionality of airpath components
- Maximising pressure charging system efficiency to ensure optimal overall powerpack efficiency
- Quantifying flow parameters of airpath components (particularly inlet ducting) and designing the applied guide lines
- Improvements in vehicle transient performance, pressure charging system performance and NVH characteristics

12:45 Network luncheon
14:15 Numerical and experimental investigation of the
performance of a turbocharger compressor under
low pressure exhaust gas recirculation operation
- Introduction of the developed and investigated geometries
- Capability of numerical tools to predict the changed inlet flow conditions due to the mixer and its influence on the performance behaviour of the compressor
- Numerical investigations – Influence of the mixer geometries on the performance behaviour
- Design requirements for a mixer geometry in order to keep the influence on the performance as small as possible
