Aerothermal Optimization of Turbine Squealer Tip Geometries With Arbitrary Cooling Injection

Journal of Turbomachinery, 2019
Abstract The optimization of the turbine rotor tip geometry remains a vital opportunity to create more efficient and durable engines. Balancing the aerodynamic and thermal aspects, while maintaining the mechanical integrity, is key to reshape one of the most vulnerable and life-determining parts of the entire turbine. The ever-increasing

Innovative Framework for Robustness Analysis of Blade Multicavity Squealer Tip Aerothermal Performance

Journal of Thermophysics and Heat Transfer
Gas turbines are subject to various geometric and operational uncertainties, which are often overlooked in conventional research. Therefore, conclusions derived from a deterministic approach may not accurately reflect the actual gas turbine operation.

Effect of Suction Side Squealer Tip Height on Blade Tip Film Cooling in a Transonic Cascade

Volume 5: Energy Storage; Fans and Blowers; Heat Transfer: Combustors; Heat Transfer: Film Cooling
Abstract Several studies have identified that using a suction side squealer on the blade tip is beneficial for reducing leakage flow, while achieving comparable film cooling effectiveness to a full squealer. The suction side squealer increases the local pressure on the tip, and leakage through the gap is reduced.
