Abstract
Cilj ovoga rada je ispitati utjecaj različitih oblika ulazne sekcije, takozvanih milimiješala, na razvoj profila strujanja u milireaktorima u višefaznom, nemješljivom sustavu ulje-voda. U tu svrhu dizajnirana su tri reaktora okruglog poprečnog presjeka kanala, φ = 2 mm s duljinom kanala l = 640 mm i milimiješala T-oblika, J-oblika i Y-oblika. Modeli milireaktora nacrtani su u računalnom programu za 3D modeliranje ANSYS i izrađeni tehnologijom aditivne proizvodnje na uređaju Ultimaker to Go. U sva tri milireaktora proveli su se eksperimenti pri istim volumnim protocima, odnosno, jednakim vremenima zadržavanja, τ prilikom čega su praćene i opisane pojave različitih režima strujanja unutar cijevi milireaktora. Provedeni eksperimenati ukazuju da oblik ulazne sekcije (milimiješalo) uvelike utječe na razvoj profila strujanja u milireaktorima pri čemu se najčešće pojavljuje segmentirano strujanje.
Abstract (english)
The aim of this thesis is to test influence of different entry sections, so called mili mixers, on the development of fluid flow in multiphased, non-mixing system oil-water. For this purpose three reactors with diameter of φ = 2 mm and channel lenght of l=640 mm have been designed with three different milimixers: T-shape, J-shape and Y-shape. Models of milireactors are made in computer software for 3D modeling ANSYS and made with additive manufacturing technology on Ultimaker to go. Experiments were made in all three milireactors at the same volumetric flow rate which means in the same retention time, τ, and at during which notes and description of the flow was made. Experiments have shown that the shape of entry section (milimixer) greatly influences the development of fluid flow in milireactors where the most common type of flow is segmented flow.
