RISInvestigation of a Rotor Blade With Tip Cooling Subject to a Nonuniform Temperature Profile
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: One of the challenges in the design of a high-pressure turbine blade is that a considerable amount of cooling is required so that the blade can survive high temperature levels during engine operation. Another challenge is ...
Effect of Turbine Blade Tip Cooling Configuration on Tip Leakage Flow and Heat Transfer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The pressure difference between suction and pressure sides of a turbine blade leads to tip leakage flow, which adversely affects the first-stage high-pressure (HP) turbine blade tip aerodynamics. In modern gas turbines, ...
Uncertainty Analysis of Heat Transfer Predictions Using Statistically Modeled Data From a Cooled 1 1/2 Stage High Pressure Transonic Turbine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper compares predictions from a 3D Reynoldsaveraged Navier–Stokes code and a statistical representation of measurements from a cooled 11/2 stage highpressure transonic turbine to quantify predictive process ...
Heat Transfer for the Film Cooled Vane of a 1 1/2 Stage High Pressure Transonic Turbine—Part II: Effect of Cooling Variation on the Vane Airfoil and Inner End Wall
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The impact of film cooling on heat transfer is investigated for the highpressure vane of a 11/2 stage highpressure turbine operating at design corrected conditions. Cooling is supplied through three independently controllable ...
Heat Transfer for the Film Cooled Vane of a 1 1/2 Stage High Pressure Transonic Turbine—Part I: Experimental Configuration and Data Review With Inlet Temperature Profile Effects
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper investigates the vane airfoil and inner endwall heat transfer for a fullscale turbine stage operating at design corrected conditions under the influence of different vane inlet temperature profiles and vane ...
