In high-pressure single flow Steam Turbines, sealing of the radial gap between rotating and stationary parts in the front end of the turbine is a known design challenge. A traditional solution to control and reduce the leakages between the stationary

In this work, an in-house developed multiphysics unsteady approach (U-THERM3D) is employed to compute wall temperatures in a loosely coupled manner for a model aero-engine combustor, fueled with a non-premixed ethylene/air mixture and representative
