Steady state design and thermal characteristics of a gas turbine blade with lateral holes using finite element analysis [PDF]

open access: yesMATEC Web of Conferences
Turbine blades are the separate components that make up the turbine section of a steam or gas turbine. The blades must transform the high-temperature, high-pressure gas that the combustor produces into energy.

Research of electric power regeneration using automotive cooling fan (Improvement of wind turbine efficiency by high solidity rotor)

open access: yesNihon Kikai Gakkai ronbunshu, 2015
This work aims at developing a new cooling fan for vehicle engine. This fan can operate as a cooling fan at low vehicle speed. At high vehicle speed, however, the fan is rarely used as a cooling fan. Therefore the fan can be used as a wind turbine, which

Combined Process‐ and Phase‐Field‐Simulation to Predict the Microstructure of Single‐Crystal Ni‐Based Superalloys

open access: yesAdvanced Engineering Materials, EarlyView.
A combined finite element and phase‐field approach predicts the evolution of microstructure during the directional solidification of Ni‐based superalloys. The model reveals how withdrawal rate, temperature gradient, and wall thickness control the dendrite spacing, highlighting the strong effect of surface regions in thin sections where dendrite growth ...

Low‐Angle Grain Boundaries and Re‐Segregation in Single‐Crystalline Ni‐Base Superalloys

open access: yesAdvanced Engineering Materials, EarlyView.
This work demonstrates that Re‐segregation at low‐angle grain boundaries (LAGBs) in Ni‐base superalloys is influenced by misorientation angle. Advanced microscopy and atom probe tomography reveal that higher misorientation angles increases Re‐segregation.
