MODEL VAL1DATION 46 the mean and standard deviation are 0.01% and 2.0%. respectively. The large errors in prediction of power a t inlet qualities of 99% may indicate that power is not absolutely independent of inlet quality as assumed by the model. Predictions of efficiency suffered from the combination of errors in prediction of power and mass flow rate. Some predictions for efficiency differed fron the measured values by as much as 2.1% absolute and 5.2s of the tested value. In general, the efficiency predictions were mediocre with a mean and standard deviation of errors expessed as percentage of tested value of 0.8% and 2.9X, respectively. The main use of the model will be in the optimization af the hybrid system. This optimization only requires prediction of the mass flow rate, exhaust quality and power. The efficiency of the Lysholm engine alone is not required. The lack of accuracy in efficiency prediction is thus not critical and should not hamper the application of the model. The attempt to locate the efficiency peak using the model was only partially successful. Testing of the engine a t the predicted peak conditions showed an efficiency of over 42.1%. This is somewhat lower than the 43.3% predicted. Other operating conditionsin the same region, tested during the model validation and during the completion of the data matrix, produced efficiencies of over 43%. These variations are within the range of obseved experimental error and repeatability. For an analysis o f t h e experimental errors, refer to t h e Appendix. The combination of the flatness of the efficiency peak and the experimental error make it very difficult to locate the exact optimum operating point. The model appears to be able to locate only the region of highest efficiency. Because of the flatness and broadness of the peak, this is all that is required oforcan be expected fran the model. \PDF Image | EMPIRICAL MODELING OF A LYSHOLM HELICAL SCREW EXPANDER
