One of the important challenges in gas turbine design is the cooling of the turbine blades due to high operating temperatures. A common approach to this problem is circulating a coolant or cool air in channels bored on the turbine blades. Usually, it is very difficult to perform experiments to obtain information about flow conditions and properties in these channels. I used a home-brewed 3-D spectral methods code to simulate the fluid flow in inclined coolant channels driven by natural as well as forced convection. The channels are taken as asymmetrically heated from the top and the bottom to account for the temperature or heat flux differences. In this abstract, the results for a free convection of water in an inclined channel are given and compared with the horizontal channel case .

Classical Aeroelastic Stability Analysis of Large Composite Wind Turbine Blades
Farsadi, Touraj; Kayran, Altan (2016-01-04)
To achieve higher energy production bigger wind turbine systems with very long blades are increasingly used in the wind turbine industry. As the length of the wind turbine blades is increased, blades become more flexible in bending and torsion. Increased bending and torsional flexibility of long wind turbine blades may cause torsional divergence and flapwise bending-torsion flutter at high speeds. Therefore, it is important that aeroelastic stability characteristics of the blades be investigated to ensure t...
Structural Performance and Power Production of Wind Turbine Systems with Bend-Twist Coupled Blades in Underrated Wind Conditions
Şener, Özgün; Kayran, Altan (2018-01-12)
The implementation of bend-twist coupling effect on wind turbine blades on the structural performance and power production of wind turbine system exposed to underrated wind conditions are studied. The structural performance of wind turbine systems are evaluated by the decrease in damage equivalent loads in the whole wind turbine system and reduction in maximum fiber direction stresses in the blades with the exploitation of off-axis plies in the main spar caps of the wind turbine blades. Wind turbine models ...
Delamination-Debond Behaviour of Composite T-Joints in Wind Turbine Blades
Gulasik, H.; Çöker, Demirkan (2014-06-20)
Wind turbine industry utilizes composite materials in turbine blade structural designs because of their high strength/stiffness to weight ratio. T-joint is one of the design configurations of composite wind turbine blades. T-joints consist of a skin panel and a stiffener co-bonded or co-cured together with a filler material between them. T-joints are prone to delaminations between skin/stiffener plies and debonds between skin-stiffener-filler interfaces. In this study, delamination/debond behavior of a co-b...
Simulation of a non-premixed swirl burner
Solmaz, Mehmet Burak; Uzol, Oğuz; Uslu, Sıtkı; Department of Aerospace Engineering (2014)
Flame stabilizing in a gas turbine combustion chamber is one of the designing issues. Non-premixed swirling flames are commonly applied to aerial vehicles’ combustors due to their advantages in flame stabilizing and flame length shortening. However, swirling flows are very complex and hard to simulate even without reaction. Previous studies have showed that Large Eddy Simulation (LES) is able to predict swirling flow with a good degree of accuracy. On the other, it is quite expensive and is still far away f...
Experimental Study of a TLP Offshore Floating Wind Turbine
Oğuz, Elif; Clelland, David; İncecik, Atilla; Dai, Saishuai; López, Juan Amate; Sánchez, Gustavo (null; 2016-07-18)
Tank testing in a wind and wave environment is a key part of the design process for the development of an offshore floating wind turbine. The current paper describes an extensive experiment campaign carried out at the Kelvin Hydrodynamics Laboratory at the University of Strathclyde to determine the hydrodynamic performance of the Iberdrola TLPWIND offshore floating wind turbine with the NREL 5MW reference turbine over a range of environmental conditions. Tests were carried out for 70m water depth and the de...
