As improved efficiency goals require ever smaller gaps between rotating turbomachinery blade tips and stationary outer casings, it becomes more important to understand the physics of what happens when a blade tip rubs against the casing. A key piece

Axial gas turbines set up highly complex unsteady flow fields, and the incorporation of cooling further complicates the flow. Due to time and computational resource constraints, the design cycle for modern gas turbines relies heavily on steady-state
