Apstrakt

Sve termofizičke karakteristike prehrambenih materijala osim dufuzivnosti mogu se relativno lako odrediti eksperimentalno. Osnovni problem određvanja difuzivnosti je merenje profila vlage u materijalu tokom procesa sušenja. U radu je analizirana mogućnost istovremenog određivanja difuzivnosti i ostalih termofizičkih karakteristika jabuka i koeficijenata konvektivnog prenosa toplote i materije, primenom inverznog postupka. Inverzni postupak se bazira na nalaženju minimuma funkcije kvadrata odstupanja izmerenih od proračunatih vrednosti temperatura listića jabuka tokom procesa sušenja. U tu svrhu primenjena je Levenberg-Marquardt-ova metoda. Za optimalno dizajniranje eksperimenta sprovedena je analiza relativnih temperaturskih koeficijenata osetljivosti i determinante osetljivosti.
