Turbine Blade Tip Cooling and Heat Transfer

ii ACKNOWLEDGEMENTS Behind every success, there is inspiration or support of at least one person. In my case, it was a group of people including my mentor, my family, and my friends. First of all, I would like to thank Dr. Srinath Ekkad for his guidance, wisdom, and financial support. I do not think many advisors would go to the lab to help his student running an experiment. Whenever I had any ...

Effect of Inlet Geometry on the Turbine Blade Tip Region Heat Transfer Coefficient and Effectiveness

An experimental investigation of the local film cooling effectiveness and heat transfer coefficient downstream of a row of elongated holes in a simulated axial turbine blade tip is presented. Film cooling is needed to protect the turbine blade tip region from high heat transfer rates, especially when cooling by convection is insufficient to keep the temperature distribution of the blade within ...

Large-eddy simulations of flow and heat transfer around a low-Mach number turbine blade

Modeling of wall bounded flows and conjugate heat transfer (CHT) is known to be a challenging task for Large-Eddy Simulation (LES). In the boundary layers, the inertial and dissipative scales have similar sizes, which implies relying on different modeling approaches than those used in free turbulent flows. To this aim, a numerical database of highly-refined LES and CHT simulations is built and ...

Experimental measurement of heat transfer coefficient and mass of deposited CaSO4 in subcooled flow boiling condition

Fouling is a common, fundamental and costly problem in heat transfer systems, which reduces thermal efficiency of equipment, increases the energy loss and causes strong damage to the heat transfer equipment in various industries. The main causes of fouling on the heat transfer surfaces are salts with inverse temperature-solubility in the fluid which calcium sulfate is one of the most important ...

Investigation of Heat Transfer Coefficient of Ethylene Glycol/ Graphenenanofluid in Turbulent Flow Regime

In the present work, graphene was synthesized by chemical vapor deposition (CVD) method. The structure of graphene was then confirmed by X-Ray diffraction (XRD) and scanning electron microscope (TEM) images. After that, mixed acid method (H2<span style=...
