Summary: 

This test case concerns the spanwise periodic DNS or LES of the transitional and separated flow on the T106A and T106C subsonic turbine cascades. These are well-known test cases for assessing transition models for low Reynolds numbers. The first test case concerns the T106A at Re=60.000, while the T106C is computed at Re=80.000. As the inlet turbulence is very low, both flows feature laminar separation and transition in the reattachment zone or in the wake.

Participants should run both cases on either a suite of block-structured or unstructured hexahedral meshes, which will be generated and provided on request.

 

Features and challenges: 

Curved geometry

Unsteady flow

Transonic flow

Transitional flow

Direct Numerical Simulation (DNS)
