This paper proposes an efficient gradient-based optimization procedure for black-box simulation codes and its application to the fluid-dynamic design optimization of the intake of a small-size turbojet, at high load and zero flight speed. Two simplified design criteria have been considered, which avoid to simulate the flow in any turbojet components other than the intake itself. Both design optimizations have been completed in a computational time corresponding to that required by eight flow analyses and have provided almost coincident optimal profiles for the intake. The flow fields computed with the original and the optimal profiles are compared to demonstrate the flow pattern improvements that can be theoretically achieved. Finally, the original and the optimal profiles have been mounted on the same small-size turbojet and experimentally tested, to assess the resulting improvements in terms of overall performances. All numerical and experimental results can be obviously extended to the intake of a microturbine for electricity generation.

In the paper, the development of an integrated experimental-numerical case study for a university course of Fluid Dynamic Design of Turbomachinery (FDDT) is presented. Since 2004, a FDDT course has been held at the Engineering Department of the University of Ferrara (Italy). The basic idea of the FDDT course is to introduce the basic and advanced ideas beyond the design of turbomachinery supported by the use of integrated three-dimensional tools. Within the course, great effort has been devoted to practical experience, both numerical and experimental. In particular, the study of a simple but exhaustive geometry may represent a good exercise where students can practically and effectively train. For this reason, during the FDDT course, a centrifugal pump has been studied both experimentally and numerically as a test geometry. In the paper, the phases necessary to carry out this kind of project are presented and discussed.
