Abstract

U mnogim granama tehnike javljaju se problemi merenja protoka fluida. Merne blende, zbog svojih mnogih prednosti predstavljaju najzastupljeniji instrument za merenje protoka fluida kroz cevovode. Sa druge strane njihova upotreba povećava troškove rada industrijskih postrojenja i cevovoda. U ovom radu dizajnirana su i ispitana tri nova oblika mernih blendi. Njihov cilj je bio ušteda energije, a samim tim i smanjenje troškova rada. Novi oblici mernih blendi, kao i jedna standardnog oblika koja je poslužila kao referentna, dizajnirani su u programskom paketu SolidWorks. Ušteda energije je postignuta dizajnom koji smanjuje otpor merne blende kao elementa cevovoda. Zatim su, prema predloženom algoritmu, dizajnirani oblici ispitani pomoću simulacije računarske dinamike fluida (RDF) u programskom paketu COMSOL Multiphysics i primenom tehnologije 3D štampanja, FDM postupkom (eng. Fused Deposition Modeling), izrađeni i ispitani u laboratorijskim uslovima. Rezultati laboratorijskih ispitivanja su prikazani uporedo sa rezultatima RDF simulacije. Dobijeni rezultati pokazuju znatan efekat uštede energije. Utvrđeno je da se pomoću RDF simulacije mogu dobiti podaci na osnovu kojih se može doneti odluka da li novi oblik merne blende treba korigovati ili ima smisla pristupiti laboratorijskom ispitivanju.
