A fully three-dimensional compressible inverse design method for the design of radial and mixed flow turbomachines in described in this paper. Two approaches are presented for solving the compressible flow problem: approximate and exact approaches.

In this paper, the potential of a 3D inverse design method, in which the blade geometry is computed for a specified circulation distribution (directly related to blade loading), as a means of using the flow information obtained from CFD predictions and detailed measurements to effect systematic improvements in turbomachinery design has been explored.

The design of the compressor aims to cover a wide operation range. A ‘back-to-back’ configuration is therefore selected considering its advantage on performance range.

The customer, one of the world’s leading HVAC manufacturers, required the design of a new range of chillers using R1234ze(E) refrigerant. The chiller uses a 2-stage in-line compressor. Both compressors and the return channel need to be designed.

To compare the performance of inducers with different blade loadings, a three-dimensional inverse design method was applied to control the blade loading distribution of inducers. This paper has been presented during the ASME 2002 Fluid Engineering Division Summer Meeting.

In this paper, a 3D inverse design code TURBOdesign1 is applied in a parametric way to the design of the blade geometry of an axial box fan.

In this consultancy, ADT engineers were asked to develop a high performance, 3-stage axial LP turbine in a very short time frame to help win a competitive bidding process.

When Avio Aero launched an internal review of their design systems, it lead to a powerful revamp of the whole aero turbines design process. This led to an improvement in tool quality as well as overall methodology.
