RISLive-Bed Pier Scour in a Covered Flow
Publisher: American Society of Civil Engineers
Abstract: Results are presented for a novel experimental investigation of live-bed scour at a cylindrical pier in covered flow. The experimental campaign also comprehended a reference scour test in clear-water conditions. Results ...
Frequency of Clouds in Height Layers for Berlin (Tempelhof)
Publisher: American Meteorological Society
Abstract: This article investigates the feasibility of establishing charts of frequency occurrence of clouds within given height layers from tabulations of cloud base frequencies. The general method is described and simplification ...
Enhanced One‐Dimensional Modeling of Transport in Rivers
Publisher: American Society of Civil Engineers
Abstract: Longitudinal dispersion of substances transported in rivers is caused by variations of the advective velocity over the river cross section and by transverse mixing. This two‐dimensional nature of the process is not accounted ...
Effects of Uncertainty and Quasi-Chaotic Geometry on the Leakage of Brush Seals
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This article presents a brief review of the experimental and theoretical state of the art regarding the leakage flow prediction of brush seals. The authors model a computational fluid dynamics (CFD)-based approach for the ...
Spatial Correlations of Trabecular Bone Microdamage with Local Stresses and Strains Using Rigid Image Registration
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Although microdamage is known to accumulate in trabecular bone with overloading and aging, the tissue-level stresses and strains associated with local bone failure are not well known. Local ...
First and Second Law Analysis of Intercooled Turbofan Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Although the benefits of intercooling for aeroengine applications have been realized and discussed in many publications, quantitative details are still relatively limited. In order to strengthen the understanding of ...
Frequency Distribution of Wind Speed Near the Surface
Publisher: American Meteorological Society
Abstract: The purpose of this paper is to provide information about frequency distributions of wind speed near the surface of the earth. There has been a recent increased interest in this topic because of the potential for obtaining ...
The Effect of Clouds and Wind on the Difference in Nocturnal Cooling Rates between Urban and Rural Areas
Publisher: American Meteorological Society
Abstract: The urban warming effect is interesting in its own right and is important for understanding global warming. The aim of this study is to determine how the urban warming effect changes with cloud conditions and with wind ...
Experimental and Numerical Study of Laminar-Turbulent Transition on a Low-Pressure Turbine Outlet Guide Vane
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work presents an experimental and numerical investigation of the laminar-turbulent transition and secondary flow structures in a turbine rear structure (TRS). The study was executed at engine representative Reynolds ...
