![]() Single nozzle spray drift measurements of drift reducing nozzles at two forward speeds Comparison of calculated and experimental data are shown and compared Strain fields were measured using high-strain gauges, which were located in different distances from center of nozzle radius, thus different stress concentration values were reached. Experimental verification was carried out on model nozzles loaded statically as well as by repeated loading, both in elastic-plastic region. Comparison of results using different analytical methods - Neuber's, Hardrath-Ohman's as well as equivalent energy ones, used in different reactor Codes - is shown. Calculation using analytical methods was performed. While primary nozzle has an ID equal to 850 mm, the model nozzle has ID equal to 280 mm, and was made from 15Kh2NMFA type of steel. Program of experimental verification of stress/strain field distribution during elastic-plastic loading of a reactor pressure vessel WWER-1000 primary nozzle model in scale 1:3 is presented. Reactor pressure vessel nozzles are characterized by a high stress concentration which is critical in their low-cycle fatigue assessment. International Nuclear Information System (INIS) ![]() Stresses in reactor pressure vessel nozzles - Calculations and experiments For the future more Laval nozzles with different geometries will be produced and additional measurements with these new nozzles at the PANDA cluster-jet target prototype towards higher performance will be realized. Initial measurements of these nozzles at the PANDA cluster-jet target prototype and the investigation of the cluster beam origin within the nozzle will be presented and discussed. Optimizations on the recently developed production process and the fabrication of new glass nozzles were done. for the PANDA experiment, and opens the way for future investigations on the cluster production process to match the required targets performance. The possibility to produce new fine Laval nozzles ensures the operation of cluster-jet targets, e.g. The production of such nozzles with their complex inner geometry represents a major technical challenge. For the production of clusters the geometry of the nozzle is crucial. A cluster source generates a continuous flow of cryogenic solid clusters by the expansion of pre-cooled gases within fine Laval nozzles. Therefore, a cluster-jet target is planned to be the first internal target for the PANDA experiment at FAIR.

Jugs may be sold with attached or separate closures and may be pre-sterilized, cleaned, or otherwise treated for specific uses.Energy Technology Data Exchange (ETDEWEB) Often used for packaging chemicals, plastic-coated glass jugs can temporarily contain their contents if closed and accidently broken. Available in clear and amber glass, plastic-coated glass, and natural and colored plastic. They typically have wide bodies, a small mouth or opening, and a built-in handle to facilitate pouring. Jugs may be best suited for large quantities of liquids. Most jars are sold with attached or separate closures, and may be processed (sterilized or cleaned) for specific purposes. Choose jars made from clear glass or natural plastics for maximum visibility and amber-tinted glass and plastic for light-sensitive materials. Other styles include bell, vacuum, and other specialty jars. Like bottles, they are made from clear or colored glass or natural or colored plastics. Lab jars have wider openings than bottles and are more often used for dry or semi-solid materials. Most bottles are sold with attached or separate closures, and can be sterilized, clean, or otherwise processed for specific applications. Choose clear glass or natural plastics for maximum visibility and amber-tinted glass and plastic for light-sensitive materials. Bottles may be made from glass (clear or amber), natural or colored plastics, plastic-coated glass, and sometimes metal. Bottles are available in specific shapes, like Boston rounds, packers, square, media, and other specialty styles. ![]() Bottles typically have an opening that is smaller in diameter than the rest of the container. Lab bottles are most often used for chemicals, solvents, and other liquids.
