- •
We numerically investigate the endwall with upstream slot for a gas turbine blade.
- •
The influences of mass flow ratio of purge flow and ejection angle of slot have been studied.
- •
The flow structure near the endwall with purge flow is further discussed and presented.
- •
The effects of the purge flow on the endwall film cooling, heat transfer characteristics and aerodynamic losses are studied.
