Summary:

The paper analyses a procedure, based on thermodynamics concepts, to calculate the isentropic outlet temperature taking into account the changes in specific heat during the thermodynamic process; the results obtained were compared whit those given by the traditional methods. Besides, using data from tests, performed in a specific turbochargers test bench, the differences in isentropic efficiency have been evaluated and compared too.Moreover, another factor related with the influence of the gas specific heat on turbocharger performance is the effect that the humidity contents on gas has on the efficiency calculations. Normally, ambient conditions are taken into account just to obtain the corrected values of the main variables in compressor calculations, however the humidity ratio is not included and its effect is neglected. This study presents also a theoretical- experimental analysis about the effect of taking into account this factor
