RISPulsed Thermal Imaging Measurement of Thermal Properties for Thermal Barrier Coatings Based on a Multilayer Heat Transfer Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Thermal properties of thermal barrier coatings (TBCs) are important parameters for the safe and efficient operation of advanced turbine engines. This paper presents a new method, the pulsed thermal imaging–multilayer ...
Quantitative Three Dimensional Imaging of Heterogeneous Materials by Thermal Tomography
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Infrared thermal imaging based on active thermal excitations has been widely used for nondestructive evaluation (NDE) of materials. While the experimental systems have remained essentially the same during the last few ...
Validation of a Thermodynamic Retrieval Technique by Application to a Simulated Squall Line with Trailing Stratiform Precipitation
Publisher: American Meteorological Society
Abstract: A thermodynamic retrieval technique, which uses the equation of motion in conjunction with the thermodynamic equation, is validated in a two-dimensional numerical model simulation of a squall line with a trailing stratiform ...
Eddy Viscosity and Reynolds Stress Models of Entropy Generation in Turbulent Channel Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents new models of entropy production for incompressible turbulent channel flows. A turbulence model is formulated and analyzed with direct numerical simulation (DNS) data. A Reynolds-averaged Navier–Stokes ...
A Comparison between the 4DVAR and the Ensemble Kalman Filter Techniques for Radar Data Assimilation
Publisher: American Meteorological Society
Abstract: A four-dimensional variational data assimilation (4DVAR) algorithm is compared to an ensemble Kalman filter (EnKF) for the assimilation of radar data at the convective scale. Using a cloud-resolving model, simulated, ...
Cold Metal Transfer Joining of Aluminum AA6061 T6 to Galvanized Boron Steel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Along with the development of automobile industry for lightweight vehicles, more and more advanced and ultrahigh strength steels (e.g., hot stamping steel) have been used for automotive applications. Making use of the high ...
Determining Wave–Turbulence Interactions in the Stable Boundary Layer
Publisher: American Meteorological Society
Warm Upper-Level Downdrafts Associated with a Squall Line
Publisher: American Meteorological Society
Abstract: Thermodynamic retrieval analysis applied to a composite of dual-Doppler radar data obtained in the 10?11 June 1985 PRE-STORM (Preliminary Regional Experiment for STORM-Central) squall line and a model simulation of a similar ...
A Cable-Borne Tram for Atmospheric Measurements along Transects
Publisher: American Meteorological Society
Abstract: A system to make atmospheric measurements from a moving trolley suspended by a stretched cable has been developed. At present, these measurements consist of wind velocity, temperature, humidity, and carbon dioxide ...
Ocean Wave Slope Observations Using Radar Backscatter and Laser Altimeters
Publisher: American Meteorological Society
Abstract: Combination of laser and radar aboard an aircraft is used to directly measure long gravity wave surface tilting simultaneously with nadir-viewing microwave backscatter from the sea surface. The presented dataset is extensive, ...
