RISExperimental Investigation Into the Relationship Between the Roughness Height in Use With Nikuradse or Colebrook Roughness Functions and the Internal Wall Roughness Profile for Commercial Steel Pipes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The relationships between the sand grain roughness height (ks) in use with Nikuradse or Colebrook correlations for the roughness function (RF) and the internal pipe wall roughness element described by the rootmeansquare ...
Insight Into the Interaction Between Flow Field and Acoustic Field of Turning Flow Into a Side Branch Against a Deadleg
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Acoustic resonances in internal flows can cause noise, vibration, and even equipment damage. One geometry prone to acoustic resonance is a deadleg at the point where the main flow turns into a side branch. Here, we report ...
Pneumatic Testing of Piping Assemblies: Criteria for Stored Energy and Pinhole Leak Detectability
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Pneumatic testing is beneficial as an alternative to hydrotesting particularly in remote areas where access to hydrotest fluids becomes logistically difficult or impossible. In some cases, above-ground pipe supports cannot ...
Interfacial Contamination Between Batches of Crude Oil Due to Dead Legs in Pump Station Piping
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Some oil pump station design layouts may contain multiple deadlegs. During the transportation of heavy crude through the pump station, these deadlegs will be filled with this crude. When a light crude batch is introduced ...
Evaluation of Gas Turbine Outboard Bleed Air on Overall Engine Efficiency and CO2e Emission in Natural Gas Compressor Stations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Gas turbine (GT) engines employed in natural gas compressor stations operate in different modes depending on the power, turbine inlet temperature, and shaft speeds. These modes apply different sequencing of bleed valve ...
Recoverable Versus Unrecoverable Degradations of Gas Turbines Employed in Five Natural Gas Compressor Stations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Gas turbines (GT), like other prime movers, experience wear and tear over time, resulting in decreases in available power and efficiency. Further decreases in power and efficiency can result from erosion and fouling caused ...
Measurements of Decompression Wave Speed in Simulated Anthropogenic Carbon Dioxide Mixtures Containing Hydrogen
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In order to determine the material fracture resistance necessary to provide adequate control of ductile fracture propagation in a pipeline, a knowledge of the decompression wave speed following the quasi-instantaneous ...
Measurements of Decompression Wave Speed in Binary Mixtures of Carbon Dioxide and Impurities
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Shock tube tests were conducted on a number of binary CO2 mixtures with N2, O2, CH4, H2, CO, and Ar impurities, from a range of initial pressures and temperatures. This paper provides examples of results from these tests. ...
Measurements of Decompression Wave Speed in Pure Carbon Dioxide and Comparison With Predictions by Equation of State
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Carbon dioxide capture and storage (CCS) is one of the technologies that have been proposed to reduce emissions of carbon dioxide (CO2) to the atmosphere. CCS will require the transportation of the CO2 from the “capture†...
Measurements of the Stack Metal Temperature During a Natural Gas Blowdown Event Through a Full Bore Blowdown Valve
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experiments were used in conjunction with a compressible flow model to investigate the temperature recovery phenomenon along a blowdown stack during a highpressure natural gas pipeline blowdown. The test rig involved ...
