Abstract: Piping systems adapted for handling fluids such as steam and various process and hydrocarbon gases through a pressure-reducing device at high pressure and velocity conditions can produce severe ...

Abstract: The dependence of plume growth rate on plume size is discussed. It is shown that the growth rates estimated by techniques used in some widely distributed puff models can be in error by as much as two orders of magnitude, ...

Abstract: In photovoltaic systems, the encapsulant material that protects the solar cells should be highly transparent and very durable. Glass satisfies these two criteria and is considered a primary ...

Abstract: The contents of the paper cover: a brief history of some concepts of the theory of gearing, and new developments in this area, (i) theory of enveloping curves and surfaces, (ii) simulation ...

Abstract: Relatively high concentrations of antibiotic-resistant bacteria are often found in the anthropogenically impacted aquatic environment. This is an emerging concern, and it is not clear which mechanism is responsible: external ...

Abstract: Several photochemistry field studies that included OH measurements have been conducted in the past few years. Two of these studies were also informal OH intercomparisons. As a result of these studies there have been several ...

Abstract: Low-frequency acoustic vibration of a vertical gas turbine recuperator during cold start-up is described. The vibration was identified as fluid-thermoacoustic instability driven by a modified ...

Abstract: Necessary conditions of undercutting of gears, necessary and sufficient conditions of the existence of the contact lines envelope on the generating surface are found. The conditions are studied ...
