The proposal is based on the innovative techniques, and makes use also of the latest developments in the field of labyrinth seal testing and flow characterization. Various modern equipments and processing methods will be used.
One of the ground-breaking innovations witch the proposed infrastructure will be able to measure the radial clearance during testing runs while the rotor (disk + labyrinth seal) is rotating. In this way, the real clearance value during testing could be used in optimizing the mathematical model of the sealing.
Another ground breaking innovation is that by automatically controlling the test vehicle, the testing time will be reduced. Another way to reduce the time is to reduce the number of operations done in order to prepare the test vehicle. The automation of the test bench will ensures constant working parameters and eliminates human factor errors, the testing process being independent of the operator. The degree of automation will be carefully analyzed during the design phase. Optimization of the testing procedures refers here mainly to the sequence of tests, the sequence of changing parameters in such a way to minimize the dead times.
The additional computational resources allows to the advancement in time at much larger time steps. The advance of the numerical solution in time is achieved numerically by a dual time stepping approach that combines the advantages of implicit and explicit methods. The specific phases performed in independently determining the seal characteristics are Flow Analysis, Thermal Analysis, Structural Analysis and finally Seal Performance Analysis.
