A method for casting a turbine blade body comprises; providing a mold defining the external geometry of the blade body; providing a core defining an internal geometry of the blade body, the core comprising a main body defining an internal chamber of the blade body and having a root end and...
The paper presents recent trends in modeling jets in crossflow with relevance to film cooling of turbine blades. The aim is to compare two classes of turbulence models with respect to their predictive performance in reproducing near-wall flow physics and heat transfer The study focuses on anisotropi...
External cooling of turbine blades by film cooling is achieved by injecting relatively cooler air from the internal coolant passages out of the blade surface to form a protective layer between the blade surface and hot gas-path flow. The most important research contributions on turbine blade ...

Thus, it is very important to cool the turbine blades for a long durability and safe operation. Cooling the blade must include cooling of the key regions being exposed to the hot gas. The blade tip region is such a critical area and is indeed difficult to cool. This results from the ...
As a basic research on film-cooling of turbine airfoils the experiments of flow visualization of the water model flow was carried out. The flat plate model with a single round ejection hole was used and its flow was visualized by the dye injection and the H2-bubble tracer methods. The horse...
Apart from the internal cooling passages detailed above, there are other structures that determine the cooling efficiency of a turbine blade. The tips of turbine blades experience especially large thermal loads due to hot gases flowing through the gap between blade tip and shroud at high velocity....
