Turbulent flow over a pin fin array: parametric study
(2010-05)
Modern jet engines reach very high combustion temperatures to achieve higher thermal efficiencies which can damage the turbine blades. Damage can occur in the turbine blade due to the temperature difference between the ...
Effects of external conditions on the boundary layers of adjacent blades on a compressor cascade
(2018-12-12)
In commercial aircraft engines, improvements of 1% in overall engine efficiency represent millions of dollars in fuel savings and a considerable reduction of CO emissions. Analyzing, understanding and optimizing each process ...
Reynolds averaged and large eddy simulations of the turbulent flow in a channel with inclined and V-shaped turbulators on the walls
(2012-07)
Turbine inlet air temperatures may exceed the melting points of the turbine blade material. Proper cooling processes increase turbine blade durability as well as the engine efficiency by allowing higher combustion temperatures ...
DNS of turbulent channel flow with inclined, continuous and segmented V-shaped turbulators
(2011-05)
The cooling system of the gas turbine blades plays a critical role in increasing the thermal efficiency and power output of advanced gas turbine engines. In fact, by increasing the heat transfer, the turbine blade can ...
Numerical study of two-phase turbulent flow
(2008)
In this thesis we calculate various Lagrangian correlation functions for fluid and particle velocities along the trajectories of the particles in two-phase turbulent flow cases.
We consider the case of stationary ...
