Simulation of turbine blade trailing edge cooling [PDF]
Journal of Fluids Engineering, 2009 The cause of overprediction of cooling efficiency by unsteady Reynolds averaged simulations of turbine blade trailing edge cooling flow is investigated. This is due to the deficiency in the level of unsteady coherent energy very near to the wall. Farther

Acoustic Improvement of Stator–Rotor Interaction with Nonuniform Trailing Edge Blowing [PDF]
Applied Sciences, 2018 The results of unsteady-flow simulations and experiments are discussed to investigate active noise-reduction effects on the stator–rotor interaction in a single-stage low-speed compressor with nonuniform trailing edge blowing.

Development of smart blade technology - trailing edge flaps [PDF]
, 2014 With blade lengths presently up to 80+ m there is a need for a supplement to the standard pitch system for control of power and loads. Distributed load control along the blade span with trailing edge flaps is a promising concept where numerical simulations have shown considerable load alleviation potential.

Trailing edge noise computation of a fan blade profile [PDF]
The Journal of the Acoustical Society of America, 2008 In problem involving noise generated by fans or high-lift devices in uniform stationary flow, trailing edge noise has a primary interest. This paper proposes to study the trailing edge noise produced by a Controlled-Diffusion (CD) airfoil specially developed for automotive engine cooling by Valeo.

Study on the repair parameters for trailing‐edge bonding failure of wind turbine blade in service
Energy Science & Engineering, 2023 A numerical analysis method of trailing edge deboning is proposed in this paper. Using this method, multiple repair parameters can be quantified by analyzing aerodynamic responses and structural characteristics of the trailing edge.
