  7. Abstract:
  8. The increasing need for more efficient and environmentally friendly microturbines necessitates the utilization of compact recuperators resulting in lower fuel consumption and emissions. The goal of this research is to determine the performance behavior of a primary surface recuperator to be incorporated in a 100 kW microturbine. Primary surface recuperator, known for relatively favorable characteristics in heat transfer, low weight, and high efficiency is considered as a candidate in aviation engines. In this research, a computational model for heat transfer and pressure losses is used for the design optimization of annular involute-profile cross wavy primary surface recuperators in microturbine. The computational model is validated by comparing the results with the experimental data of Capstone microturbine. Further, an optimization for the primary surface recuperator is carried out with a focus on heat-transfer performance, weight, and pressure loss. Furthermore, a transient analysis is performed for the recuperator. Considering the results related to the thermodynamic cycle and the sensitivity analysis concerning the flight conditions and the geometry of the heat exchanger, an optimum of the operation point is determined. Results indicate of higher efficiency, lower specific fuel consumption and hence lower emissions.
