Abstract

A lumped capacity heat transfer model has been developed and compared to
measurements from a turbocharger operating on a 2.2L Diesel engine under steady
and transient conditions ranging from 1000-3000rpm and 2-17bar BMEP. The
model parameters have been estimated based on similar devices and this study
quantifies the errors associated with this approach. Turbine outlet gas temperature
prediction was improved with RMSE reduced from 29.5oC to 13oC. A sensitivity
study showed the parameters of the heat transfer model influence gas
temperatures by only ±4oC but housing temperatures by up to 80oC. Transient
simulations showed how errors in the thermal capacitance also lead to errors. This
study shows the importance of undertaking a full thermal characterisation and the
need for accurate adiabatic maps in turbocharger simulations.
