Computational Fluid Dynamic Analysis of a Vibrating Turbine Blade

Figure 2

Modelling of rotor/stator domains requires the lowest common multiple of rotor/stator blades to be modelled for continuity of flow out of one domain and into another. (a) Integer pitch ratio, all flow out of stator domain flows back into rotor domain (b) noninteger pitch ratio, has unequal flow from stator to rotor domains.
