RISPhysical Interpretation of Flow and Heat Transfer in Preswirl Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper compares heat transfer measurements from a preswirl rotor–stator experiment with three-dimensional (3D) steady-state results from a commercial computational fluid dynamics (CFD) code. The ...
CFD Analysis of Flow and Heat Transfer in a Direct Transfer Preswirl System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The accuracy of computational fluid dynamics (CFD) for the prediction of flow and heat transfer in a direct transfer preswirl system is assessed through a comparison of CFD results with ...
Prediction of Ingress Through Turbine Rim Seals—Part I: Externally Induced Ingress
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Rotationally induced (RI) ingress is caused by the negative pressure (relative to the external air) inside the wheel-space of a gas turbine; this negative pressure, which is created by the ...
Computational Fluid Dynamics Simulations of Flow and Heat Transfer in a Preswirl System: Influence of Rotating-Stationary Domain Interface
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents computational fluid dynamics (CFD) predictions of flow and heat transfer for an over-swirled low-radius preswirl system and comparison with experimental data. The rotor-stator ...
