Experimental Results with a Rain Analyzer
Publisher: American Meteorological Society
Abstract: The rain analyzer is an instrument with which the main part of the raindrop size spectrum can be determined. During measurements of the rain attenuation of millimeter waves, rainfall was recorded both with rain analyzers ...
Katabatic Flows and Their Relation to the Formation of Convective Clouds—Idealized Case Studies
Publisher: American Meteorological Society
Abstract: he formation of a convective cloud system as a result of a katabatic-induced surface cold front at the eastern Andes Mountains of South America was investigated in a numerical model study. The occurrence of this cloud ...
Analysis of Water Vapor over Nigeria Using Radiosonde and Satellite Data
Publisher: American Meteorological Society
Abstract: he Satellite Application Facility on Climate Monitoring (CM-SAF) focuses on retrieving geophysical parameters from satellite data by using inversion schemes that are based on radiative transfer theory. In this study, the ...
Generalized Split-Explicit Runge–Kutta Methods for the Compressible Euler Equations
Publisher: American Meteorological Society
Abstract: he compressible Euler equations exhibit wave phenomena on different scales. A suitable spatial discretization results in partitioned ordinary differential equations where fast and slow modes are present. Generalized ...
Forced Response Due to Vane Stagger Angle Variation in an Axial Compressor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recent developments in turbomachinery design require an improved prediction accuracy of blade vibrations to maintain safe operations. This article aims to investigate the accuracy of numerical aeroelastic approaches for ...
Aeroelastic Influence of Blade-Shaft Coupling in a 1 1/2-Stage Axial Compressor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The design process of turbomachinery is often constraint by aeroelastic phenomena. The design choices are limited by possible structural failure, which can be caused by high vibration amplitudes. In particular, damping has ...
Causes of Acoustic Resonance in a High-Speed Axial Compressor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Nonharmonic acoustic resonance was detected in the static pressure and sound signals in a four-stage high-speed axial compressor when the compressor was operating close to the surge limit. Based ...
Experimentally Verified Study of Regeneration Induced Forced Response in Axial Turbines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Geometrical variations occur in highly loaded turbine blades due to operation and regeneration. To determine the influence of such regenerationinduced variances of turbine blades on the aerodynamic excitation, a typical ...
Flow Patterns in High Pressure Steam Turbines During Low Load Operation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Due to the legislative efforts of promoting renewable energy sources, electricity from these sources is preferentially fed into the electrical grid. This requires more frequent partand lowload operation of peakand even of ...
Location and Magnitude of Heat Sources in Solid Oxide Fuel Cells
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The correct prediction of the temperature distribution is a prerequisite for the reliable determination of species and current distributions in any solid oxide fuel cell (SOFC) model. It is ...
