RISPrediction of Cascade Flows With Innovative Second-Moment Closures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We report on the performances of two second-moment turbulence closures in predicting turbulence and laminar-to-turbulent transition in turbomachinery flows. The first model considered is the one ...
Seismic Design and Analysis of Steel Plate Shear Walls with Coupling
Publisher: American Society of Civil Engineers
Abstract: Special steel plate shear walls (SPSWs) are an economical seismic lateral force resisting system used throughout North America and Japan. Architectural constraints often encourage the designer to place a pair of planar ...
Structural Uncertainty Effect on Classical Wing Flutter Characteristics
Publisher: American Society of Civil Engineers
Abstract: Flutter-critical velocity is usually estimated from deterministic analyses by assuming that physical and geometrical parameters are perfectly known. However, aleatory and epistemic uncertainties, especially those associated ...
An Integrated Particle-Tracking Impact/Adhesion Model for the Prediction of Fouling in a Subsonic Compressor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present paper reports on the analysis of the motion of adhesive particles and deposit formation in a 3D linear compressor cascade in order to investigate the fouling in turbomachinery ...
Large-Scale Cyclic Testing of Steel-Plate Shear Walls with Coupling
Publisher: American Society of Civil Engineers
Abstract: The steel-plate shear wall with coupling (SPSW-WC) system is a natural extension of the conventional steel-plate shear wall (SPSW) seismic force–resisting system. The SPSW-WC configuration is created by linking a pair of ...
Synthesis of Methanol From a Chemical Looping Syngas for the Decarbonization of the Power Sector
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: One promising pathway for carbon capture and utilization is represented by the coupling of chemical looping cycles with liquid fuel synthesis processes. Methanol is an interesting fuel for gas turbines engines, due to its ...
Engineering Method for Air-Cooling Design of Two-Seat Propeller-Driven Aircraft Powered by Fuel Cells
Publisher: American Society of Civil Engineers
Abstract: The application of fuel-cell technology to aircraft propulsion and/or energy supply is becoming of great interest for undoubted advantages in terms of pollution emissions and noise, features particularly important for ...
Air Cooling of a Two-Seater Fuel Cell–Powered Aircraft: Dynamic Modeling and Comparison with Experimental Data
Publisher: American Society of Civil Engineers
Abstract: The application of fuel cell (FC) technology to aircraft propulsion and/or energy supply is becoming of great interest for undoubted advantages in terms of pollution emissions and noise reduction. A better understanding ...
Effects of Water-to-Air Mass Ratio on Long-Term Washing Efficiency and Erosion Risk in an Axial Compressor Under Online Washing Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: One of the main reasons for gas turbines’ performance losses is the deposition of dirt on the compressor blades. Dirt deposit has to be periodically removed to keep the engine performance as high as possible. This is the ...
Experimental and Numerical Investigation of NH3/H2/N2 Combustion in a Premixed/Stratified Swirl Burner
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Interest in using renewably produced, partially cracked ammonia in gas turbines is gaining traction, but challenges relating to emissions of NOx and unburned ammonia remain. This work progresses existing research on using ...
