RISImpact of Internal Crossflow on Flow Topology Inside and Outside of Film-Cooling Holes With Varying Inclination and Supply Flow Angles: 3D Velocity Data From Magnetic Resonance Velocimetry
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Crossflow on both sides of film-cooling holes with engine-representative length-to-diameter ratios significantly impacts flow topology and cooling effectiveness in gas turbine airfoils. This experimental study ...
Influence of Channel Geometry and Flow Variables on Cyclone Cooling of Turbine Blades
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A study examining the internal cooling of turbine blades by swirling flow is presented. The sensitivity of swirling flow is investigated with regard to Reynolds number, swirl intensity, and the common geometric features ...
Influence of Combustor Swirl on Endwall Heat Transfer and Film Cooling Effectiveness at the Large Scale Turbine Rig
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: At the large scale turbine rig (LSTR) at Technische Universität Darmstadt, Darmstadt, Germany, the aerothermal interaction of combustor exit flow conditions on the subsequent turbine stage is examined. The rig resembles a ...
Assessment of the Flow Field and Heat Transfer in a Vane Cooling System Using Magnetic Resonance Velocimetry, Thermochromic Liquid Crystals, and Computational Fluid Dynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Computational fluid dynamics (CFD) is the standard tool in the turbomachinery industry to analyze and optimize internal cooling systems of turbine components, but the code applied has to be validated. This paper presents ...
