Biases of Rain Retrieval Algorithms for Spaceborne Radar Caused by Nonuniformity of Rain
Publisher: American Meteorological Society
Abstract: The biases of various rain retrieval algorithms for a spaceborne rain radar due to nonuniformity of rain are studied using simple models and an actual time sequence of rainfall rate. A conventional rain retrieval algorithm ...
A Theory of Vertical Modes in Multilayer Stratified Fluids
Publisher: American Meteorological Society
Abstract: theory of vertical modes in multilayer stratified fluids is proposed. A matrix notation is introduced to generalize the theory to an arbitrary number of layers. The properties of vertical modes including their orthogonality ...
Numerical Investigation of the Effect of Trailing Edge Thickness of Simulated Ceramic Matrix Composite Blades on Loss Profiles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Ceramic matrix composite (CMC) is an enabling material allowing higher turbine inlet temperatures and possibly resulting in better thermal efficiency of gas turbine engines. This is because CMC layers with environmental ...
Special Issue on Mesh-Based Geometric Data Processing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This special issue on Mesh-Based Geometric Data Processing consists of 10 papers selected from 27 submissions. Although covering quite diverse technical issues, these 10 papers share a common ...
Inverse Pre-deformation of Finite Element Mesh for Large Deformation Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The process of finite element analysis that deals with large deformation often produces distorted elements in the later stages of the analysis. These distorted elements lead to analysis problems, ...
Sinusoidal Variation of Wall Shear Stress in Daughter Tube Through 45 Deg Branch Model in Laminar Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present paper describes the experimental implemented work on the flow situation through a branch model having a daughter tube bifurcated from a parent tube at 45 deg. Experiments have been ...
Non-Rayleigh Scattering Effect in Rain Observations by an X- and Ka-band Dual-Wavelength Radar
Publisher: American Meteorological Society
Abstract: The effect of non-Rayleigh scattering appearing in a rain observation experiment using a dual-wavelength rain radar, is investigated. The non-Rayleigh scattering effect causes a small difference between the effective radar ...
Rainfall Parameter Estimation from Dual-Radar Measurements Combining Reflectivity Profile and Path-integrated Attenuation
Publisher: American Meteorological Society
Abstract: Rain rate estimation properties of multiparameter radar measurements combining radar reflectivity and microwave attenuations are studied through simulations using a two-year disdrometer dataset. In the first simulation, ...
Automatic Conversion of Visually Consistent Digital Maps to Conforming Geometry for Computational Fluid Dynamics
Publisher: American Society of Civil Engineers
Abstract: A method for automatic conversion of three-dimensional (3D) digital maps for visual purposes to a conforming geometry for city-scale computational fluid dynamics (CFD) is proposed in this paper. Difficulties in automatic ...
