Abstract: This paper presents the findings of an experimental and numerical investigation on the shock effect on heat transfer coefficient and filmcooling effectiveness. In this study, coolant was injected on the blade surface through ...

Abstract: Large amounts of tiny microparticles are ingested into gas turbines over their operating life, resulting in unexpected wear and tear. Knowledge of such microparticle behavior at gas turbine operating temperatures is limited ...

Abstract: An experimental study was performed to measure surface Nusselt number and film cooling effectiveness on a film cooled first stage nozzle guide vane (NGV) at high freestream turbulence, using a transient thin film gauge ...

Abstract: In modern gas turbine engines, the blade tips and neartip regions are exposed to high thermal loads caused by the tip leakage flow. The rotor blades are therefore carefully designed to achieve optimum work extraction at ...

Abstract: Detailed heat transfer coefficient (HTC) and film cooling effectiveness (Eta) distribution on a squealertipped first stage rotor blade were measured using an infrared technique. The blade tip design, obtained from the Solar ...

Abstract: When gas turbine engines operate in environments where the intake air has some concentration of particles, the engine will experience degradation. Very few studies of such microparticles approaching their melting temperatures ...

Abstract: Many gas turbine engines operate in harsh environments where the engines ingest solid particles. Ingested particles accelerate the deterioration of engine components and reduce the engine's service life. Understanding ...
