RISWeathering/Ageing of Liquefied Natural Gas Cargoes During Marine Transport and Processing on Floating Storage Units and FSRU
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The phenomenon of liquefied natural gas (LNG) cargo weathering is considered in terms of the conditions influencing boil-off gas (BOG) rates during the offshore movements and handling of LNG on marine LNG carriers (LNGC), ...
Evaluating the Impact of Free-Stream Turbulence on Convective Cooling of Overhead Conductors Using Large Eddy Simulations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The international trend of using renewable energy sources for generating electricity is increasing, partly through harvesting energy from wind turbines. Increasing electric power transmission efficiency is achievable through ...
Assessing Wellbore Stability With a Modified Lade Failure Criterion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The importance of evaluating wellbore stability in analyzing and estimating the efficiency of drilling directionally into oil and gas reservoirs is well known. Geomechanical data and failure criterion can be used to model ...
Development of an Analytical Unsteady Model for Wind Turbine Aerodynamic Response to Linear Pitch Changes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A simple unsteady blade element analysis is used to account for the effect of the trailing wake on the induced velocity of a wind turbine rotor undergoing fast changes in pitch angle. At sufficiently high tip speed ratio, ...
The Contribution of Kawada to the Analytical Solution for the Velocity Induced by a Helical Vortex Filament
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The basic solution for the velocity induced by helical vortex filament is well known as Hardin's solution, published in 1982. A study of early publications on helical vortices now shows that the Japanese scientist Kawada ...
Maximum Wall Stress on a Smooth Flat Plate Under Planar Jet Impingement
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper investigates the maximum wall shear stress value τmax and its location xmax as measured on a smooth flat plate impinged upon by a normal planar jet. τmax and xmax are found to be closely related to the stagnation ...
Hollow Blades for Small Wind Turbines Operating at High Altitudes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Since the air density reduces as altitude increases, operation of small wind turbines (SWTs), which usually have no pitch adjustment, remains challenging at high altitudes due largely to the reduction of starting aerodynamic ...
Computational Analysis of Flow and Transport Suggests Reduced Oxygen Levels Within Intracranial Aneurysms, Especially in Individuals With Sickle-Cell Disease
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Sickle cell disease (SCD) is a genetic condition characterized by an abundance of sickle hemoglobin in red blood cells. SCD patients are more prone to intracranial aneurysms (ICA) compared to the general population, with ...
Feasibility and Acute Safety Study of Radiofrequency Energy Delivery to the Vena Caval Wall Via an Inferior Vena Cava Filter in Swine
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Retrievable inferior vena cava (IVC) filters are self-expanding metallic devices implanted in the IVC to prevent migration of thrombi from the deep veins of the legs and pelvis to the lungs. The risk of complications from ...
