Symmetric airfoil geometry effects on leading edge noise.
Computational aeroacoustic methods are applied to the modeling of noise due to interactions between gusts and the leading edge of real symmetric airfoils. Single frequency harmonic gusts are interacted with various airfoil geometries at zero angle of attack. The effects of airfoil thickness and leading edge radius on noise are investigated systematically and independently for the first time, at...

متن کاملSimulation and Optimization of an Airfoil with Leading Edge Slat
A gradient-based optimization is used in order to improve the shape of a leading edge slat upstream of a DU 91-W2-250 airfoil. The simulations are performed by solving the Reynolds-Averaged Navier-Stokes equations (RANS) using the open source CFD code OpenFOAM. Gradients are computed via the adjoint approach, which is suitable to deal with many design parameters, but keeping the computational c...
متن کاملFlow and Thermal Performance of a Leading Edge Endwall-airfoil Fillet for a Gas Turbine Nozzle Guide Vane
Gas turbine engines have a high power-to-weight ratio, making them ideal for generation of aircraft thrust, and can have excellent electrical power generation efficiencies when used in a combined cycle power plant. A complex vortical flow at the junction of the nozzle guide vane airfoil and its casing (endwall) in the turbine section tends to decrease aerodynamic efficiency and increase metal t...
متن کاملSimulation of Mist Film Cooling on Rotating Gas Turbine Blades
Film cooling technique has been successfully applied to gas turbine blades to prevent it from the hot flue gas. However, a continuous demand of increasing the turbine inlet temperature to raise the efficiency of the turbine requires continuous improvement in film cooling effectiveness. The concept of injecting mist (tiny water droplets) into the cooling fluid has been proven under laboratory co...
