Direct numerical simulation of turbulent channel flow with V-shape turbulators
(2010)
Direct Numerical Simulations (DNS) are carried out to study the channel flow V-shaped roughness on both wall. The roughness is modeled by the immerse boundary method for passive heat transport in a turbulent channel flow ...
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 ...
Wind turbine modeling for computational fluid dynamics
(2012-05)
With the shortage of fossil fuel and the increasing environmental awareness,
wind energy is becoming more and more important. As the market for wind
energy grows, wind turbines and wind farms are becoming larger. ...
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 ...
