Objective
Objectives and content
Technological advances in turbomachinery, particularly at
the compressor side, either for aerospace or power
generation applications, are largely based on the
capacity of industry to model numerically the aerothermal
behaviour of advanced components.
With the trend towards higher airfoil loading in axial
compressors and the need for higher accuracy in
performance prediction (including at off-design
conditions), future simulation tools must be able to
provide better understanding of unsteady rotor/stator
interactions and the associated loss sources. These
industrial objectives clearly require an improved
knowledge at the modelisation level, supported by focused
experiments, of detailed flow processes, which were not
considered in the previous generation of design tools.
The major objectives of the project are the
understanding, evaluation and modelling of the main
unsteady loss sources in compressor rotor-stator
interactions, through new advanced experimental data
coupled to systematic and controlled numerical
simulations, at the full unsteady and quasi-steady
levels, with the objective to provide the designer with
modelling guidelines.
Unsteady phenomena are dependent on turbulent and
eventually transition effects, but it is not considered
feasible, at the present level of flow modelling, to
assess the validity of turbulence models on unsteady
data. Therefore, this effort should be performed on
steady simulations of test cases representative of the
complex 3D flow structure of advanced compressors,
The objectives of the project, are implemented through
four separate steps:
validation of turbulence models on steady single blade
row test cases, including one new set of data, by
controlled monitoring of the separate effects of grid
dependence and turbulence models, with the expectation
that the most appropriate 'steady' turbulence models will
be valid for the unsteady flow simulations.
gaining a better understanding of the unsteady multiple
blade row interactions in axial compressor stages by the
collection of new data using advanced instrumentations on
heavily instrumented rigs, of industrial relevance, with
two sets of new experiments, coupled to full unsteady
simulations on fine grids of high resolution.
based on the most adequate turbulence models, as
resulting from the validation task on the steady test
cases, improving modelling capabilities of quasi-steady
and full unsteady rotor-stator interaction models based
on the new test cases, focusing on issues of
identification and quantification of dominant unsteady
loss sources.
an action towards dissemination and communication,
involving a data base initiative and a workshop, through
a strong connection to an existing European scientific
and industrial network.
Conclusions will be drawn concerning the merits of
various models, their range of validity at design and
hopefully at off-design conditions.
A major spin-off of the technology of aero-engines is to
be found in the gas turbine industry. The present
project aims also at contributing to this objective
through exchanges of basic design methodology
improvements between the aero- engine and gas turbine
industries.
The consortium of partners is formed by five university
groups involved in experimental and CFD work on
turbomachines, one research centre dedicated to
propulsion research, three industrial partners and the
support of a European Research Network on Turbomachinery,
for an action towards dissemination and data base.
