RISHigh-Speed Recessed Conical Hybrid Bearings With Additive Manufacturing–Driven Large Gap Clearances for Integrated Bearing–Rotor Architectures of Gas Turbines: Navier–Stokes Analysis and Symbolic–Regression Correlations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Hydrostatic recessed conical bearings operating at high rotational speeds, commonly referred to as hybrid bearings, exhibit several advantages, including structural simplicity, reduced maintenance requirements, ...
Skin Cooling of Turbine Airfoils by Single-Wall Effusion—Part II: Computational Fluid Dynamics Validation and Preliminary Design Optimization on a Micro-Turbine Vane
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A reduced-order model (ROM) is developed to capture conjugate aero-thermal physics of effusion cooling in an entire micro-turbine vane/blade. The model considers a single-wall effusion scheme with internal boundary layer ...
Design Methodology and Concept Demonstration of Preassembled Additively Manufactured Turbomachinery Systems: Case Study of Turbocharger Based Medical Ventilators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present research focuses on analyzing the feasibility of manufacturing complex turbomachinery geometries in a preassembled manner through an uninterrupted additive manufacturing process, absent of internal support ...
Skin Cooling of Turbine Airfoils by Single Wall Effusion: Part I—Reduced Order Modeling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A quasi-1D conjugate reduced order model (ROM) is developed to capture aero-thermal physics of effusion cooling in turbine airfoils. This framework explicitly considers the coolant supply from the leading edge and its ...
Design-for-Additive-Manufacturing Approach for Support-Free Pre-Assembled Micro Gas Turbines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. This study presents a preliminary design approach for pre-assembled microgas turbine engines for unmanned aerospace propulsion systems, intended for fabrication via direct metal laser sintering, and demonstrates ...
