RISThe Three-Dimensional Steady Circulation in a Homogenous Ocean Induced by a Stationary Hurricane
Publisher: American Meteorological Society
Abstract: Based on the classical Ekman layer theory, a simple analytical solution of the steady flow induced by a stationary hurricane in a homogenous ocean is discussed. The model consists of flow converging in an inward spiral in ...
Kinetics Modeling on NOx Emissions of a Syngas Turbine Combustor Using Rich-Burn, Quick-Mix, Lean-Burn Combustion Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To avoid flashback issues of the high-H2 syngas fuel, current syngas turbines usually use nonpremixed combustors, which have high NOx emissions. A promising solution to this dilemma is rich-burn, quick-mix, lean-burn (RQL) ...
Combustion Tuning for a Gas Turbine Power Plant Using Data-Driven and Machine Learning Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Conventional physics-based or experimental-based approaches for gas turbine combustion tuning are time consuming and cost intensive. Recent advances in data analytics provide an alternative method. In this paper, we present ...
Experimental Investigations of Spark Ignition in a Model Combustor With Synthesis Gas
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The components of syngas derived from coal, biomass, and waste are significantly different from those of typical gas turbine fuels, such as natural gas and fuel oils. The variations of hydrogen and inert gases can modify ...
Characteristics of Flame Modes for a Conical Bluff Body Burner With a Central Fuel Jet
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Bluff body stabilized nonpremixed flames are usually used as pilot flames in leanpremixed combustors. Experiments are conducted to investigate the characteristics of the flame. Typical flame modes are investigated in both ...
Investigations of the Stabilities of Piloted Flames Using Blast Furnace Gas
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effective utilization of lowgrade energy sources generated from steelmaking processes provides not only excellent opportunities for low cost power generation but also a significant means for the reduction of greenhouse ...
Measurements and Modeling of the Dynamic Response of a Pilot Stabilized Premixed Flame Under Dual-Input Perturbation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Pilot flames have been widely used for flame stabilization in low-emission gas turbine combustors. Effects of pilot flame on dynamic instabilities, however, are not well understood. In this work, the dynamic interactions ...
Study of Residual Stress Evolution in SUS304/Q235 Bimetallic Clad Plate Butt-Welded Joints Considering Welding Sequence
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Residual stress prediction and controlling is important for structural integrity assessment of weldments. In this work, finite element (FE) and experimental methods were integrated to study the influence of welding sequence ...
A Large-Eddy Simulation–Linear-Eddy Model Study of Preferential Diffusion Processes in a Partially Premixed Swirling Combustor With Synthesis Gases
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A lean partially premixed swirling combustor operated with synthesis gases is studied using large-eddy simulation (LES). The linear-eddy model (LEM) is employed to close the unresolved scalar fluxes with the nonunity Lewis ...
