The Unsteady Temperature Field in a Turbine Blade Cooling Channel
The unsteady velocity and temperature fields are measured in a straight smooth and rib roughened square duct, representative of a stator cooling channel. The mainstream Reynolds number is 3 10. Single cold and hot wire probes as well as a dual hot/cold wire probe are used for this purpose. The experimental results are compared to the predictions from FINE, a commercial software package develope...
متن کاملA semi-analytical model for velocity profile at wind turbine wake using blade element momentum
The shape of wake behind a wind turbine is normally assumed to have a hat shape for the models used in wind farm layout optimization purposes; however, it is know from experimental tests and numerical simulations that this is not a real assumption. In reality, the results of actual measurements and detailed numerical simulation show that the velocity in wake region has a S-shape profile. Th...

متن کاملSimulating Cooling Injection Effect of Trailing Edge of Gas Turbine Blade on Surface Mach Number Distribution of Blade
In this research, a gas turbine blade cascade was investigated. Flow analysis around the blade was conducted using RSM and RNG.K-ε turbulence modeling and it is simulated by Fluent software. The results were considered for the cases as Mach number loss at the trailing edge of blade caused by vortexes that were generated at the end of blade. Effect of cooling flow through the trailing edge on th...
متن کاملCombined Radiation and Natural Convection in Participating Laminar Flow Over a Vertical Circular Pin
The interaction of thermal radiation with conduction and laminar natural convection in a vertical circular pin, situated at participating gas, is numerically investigated. An absorbing and emitting gas is considered, and treated to be a gray participating media. Under the idealizing of gray gas, the Rosselan4 approximation is employed to describe the radiative heat flux in the energy equation. ...
