Aerothermal Analysis of Rotation and Rotational Buoyancy Effect on Internal Cooling of Gas Turbine Blade- An Experimental study

Turbine blade cooling system is directly related to increasing the efficiency and power output and also growing the life time. By increasing the turbine inlet temperature, the efficiency and power output can be increased. Since the turbine blades are rotating at high rotational speeds, the blade cooling is also influenced by the rotation state. The Coriolis and centrifugal buoyancy forces are two important forces that will be created by the rotation. Therefore, in current study, the effects of Coriolis and centrifugal buoyancy forces on local and overall heat transfer coefficients in leading and trailing edges will be investigated. The experimental study will consider 5,000
