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