Abstract:

Duringthepast fewdecades,theconcept ofrefrigerantmixturefluidsisattracting moreresearchersinthe industrial applicationfor coolingequipment's.Theconcept ofmixedrefrigeranthasbecomemoreeffective whilecomparedto thebasefluids.Itismainlyusedinindustrialaswellasdomesticrefrigerants,airconditioningsystems,heatexchangers andmanymore.Inthepresentstudy, tostudythethermophysicalpropertiessuchasdensityandviscosityisusedto analyzevariouspropertiesbyconsidering 10gms ofrefrigerantmixturesuch aspropaneand ISO-butaneatdifferent compositions.Resultsare presentedforsimulations carriedoutatdifferentmassratiocompositionsvaryingwith respectto atemperaturerangeof300-350K andit isevaluatedthatvariationeffectofpressures atdifferent compositions ofarefrigerantmixture.Itisconcluded fromtheresultsthatasthetemperatureincreases,density of mixedrefrigerantincreases.Similarly, viscosityincreaseswithanincreasein temperaturefora mixed refrigerantat different compositions.
