Accurate and Affordable LES for Turbomachinery Flows – Cadence TECHTALK

Recent computational and numerical developments in Fidelity LES have made large eddy simulations (LES) efficient, accurate, and cost-efficient for turbomachinery applications.

Key developments include:
1. Advances in wall-modeled large-eddy simulation (WMLES) techniques
2. A highly efficient moving mesh solver based on Voronoi diagrams, ideal for turbomachinery flow simulations
3. GPU acceleration for high computational throughput

LES provides more accurate predictions than conventional Reynolds-averaged Navier-Stokes (RANS)-based approaches for complex, turbulent turbomachinery flows involving transition, separation, and rotor-stator interactions. This webinar will showcase the capabilities of Fidelity LES through whole-wheel simulations of a transonic fan stage to predict aerodynamic performance.
