Resumo: | At the beginning of this work, a number of issues had to be addressed. A first step in the development of the present study consists on the extensive literature review on the automotive vehicle waste heat recovery systems. The literature review was essential to identify the Rankine cycle as a high potential solution for vehicle applications. A methodology was developed and presented in order to determine which type of expander suits best in a given RC system, using the NsDs turbine chart. The parameters that have influence on the expander’s selection are: the working fluid inlet and outlet conditions (such as the temperature, pressure, type of fluid and the mass flow rate), the rotating speed and the diameter of the expander. The mass flow rate will be calculated according to the usual power extracted by the evaporator from waste heat recovery systems installed in automotive vehicles (10 kW to 500 kW). The present work presents a methodology that allows selecting an expander for a specific application. To this end, three different working fluids (R245fa, ethanol and water) were selected to demonstrate the developed methodology. The model developed in AMESim was validated by comparing the results with the ones obtained through experimental runs, which confirmed its accuracy in the results obtained. |
