Prototype designs of orifice flowmeters are commonly used in measurements. One area which has attracted considerable interest includes slotted orifices, where a single central opening is replaced by the use of several slots. This paper reports the results of numerical and experimental research of a prototype design of a slotted orifice plate. The movement of the fluid was described with use of Reynolds equations closed by the k-ε turbulence model. The calculations were performed using ANSYS Fluent software package by consideration of the fluid flow through an orifice plate and slotted orifice with the equal β ratio = 0.5. The results of calculations are compared with the measurements. Good qualitative and quantitative conformity was obtained during the study for the C flow coefficient. It was indicated that the slotted orifice generates a considerable lower pressure drop in comparison to an orifice plate while maintaining comparable level of measurement uncertainty.","PeriodicalId":142227,"journal":{"name":"Informatics, Control, Measurement in Economy and Environment Protection","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115019836","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rapidly is growing negative impact of toxic emissions of internal combustion engines (used in road transport), on the ecosystem. Apart from the problems associated with air pollution and the environment at the stage of extraction, transport and processing of liquid and gaseous hydrocarbon fossil fuels, the biggest problem is with the mass poisoning the atmosphere by products emanating from the exhaust pipes of all (land, sea and air) means of transport. Electric drive can be an effective remedy for these negative effects. Electric motors are practically emission-free and in terms of efficiency, in the conversion electrical energy into mechanical, three times superior to heat engines. In order electric trucks have been fully ecological, energy required to charge the energy containers, in the form of electrochemical batteries, must come from renewable energy sources. The basic condition for the development of electromobility based on the electric car is the need for widespread and rapid transition to production of electricity from carbon-free renewable energy sources: wind, water and sun. Published (by one of the world's leading scientific centers) results of research and analyzes show that there is a real chance to create an alternative (to the traditional system of generating electricity, based mainly on thermal power plants burning fuels), the new zero-emission system WWS ( W ind, W ater, S un), based on the use of the energy contained in the wind, flowing water, and solar radiation. The presented data show that there is a real chance of transition to WWS in the next 30 – 50 years.","PeriodicalId":142227,"journal":{"name":"Informatics, Control, Measurement in Economy and Environment Protection","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133676545","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
