Flow in a model turbine stator
Abstract
In view of the complex nature of the flowfield in the hot section of gas turbine engines, the need to predict heat transfer and flow losses, the possible appearance of separation and strong secondary flows, etc., the present effort is focusing upon a NavierStokes approach to the three dimensional turbine stator problem. The advantages of a full NavierStokes approach are clear since when combined with a suitable turbulence model these equations represent the flow and heat transfer physics. In particular, the NavierStokes equations accurately represent possible separated regions and regions of significant secondary flow. In addition, the NavierStokes approach allows representation of the entire flow field by a single set of equations, thus avoiding problems associated with representing different regions of the flow by different equations and then matching flow regions.
