20.500.12556/RUL-101903 Mikrofluidični senzor hitrosti na osnovi opazovanja gibanja delcev v stranski komori Microfluidic flow sensor based on particle tracking velocimetry in side chamber V magistrskem delu je predstavljen nov koncept merjenja hitrosti v mikrofluidičnem vezju, ki temelji na opazovanju gibanja delcev v tekočini v stranski komori, ki se ne meša z vzorcem v glavnem kanalu mikrofluidičnega vezja. Prikazane so teoretične osnove in numerična simulacija predlaganega senzorja. Opisan je postopek izdelave zasnovanega mikrofluidičnega vezja in izvedba meritev. Eksperimentalno je potrjen pojav sekundarnega toka v stranski komori in natančneje analizirano gibanje delcev v toku. Ugotovljena je korelacija med tem gibanjem in hitrostjo toka v glavnem kanalu. This master's thesis presents a new concept for velocity measurements in microfluidics, based on the observation of movement of colloidal particles in the secondary flow in the side chamber, filled with a fluid that does not mix with the sample in the main channel of the microfluidic system. First, theoretical basics and numerical simulation of proposed design are explained. Next, manufacturing of a sensor and the performed measurements are described. They are followed by detailed analysis of particle movement where correlation between the main channel flow velocity and side chamber particle movement is shown. mikrofluidika senzor hitrosti laminaren tok koloidi merjenje hitrosti s sledenjem delcev microfluidics flow sensor laminar flow colloidal particles particle tracking velocimetry true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2018-07-13 07:45:01 2018-07-13 07:45:04 2022-08-15 03:39:12 0000-00-00 00:00:00 2018 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 87409 3213924 108.pdf 108.pdf 1 4B9FDE7DE8E9450A36B934246F2BD56A 854730531f8d783f851b627bf2e9e323217ecfdc4934cf50eaf51fbf96f2c938 7323f922-a1b5-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=112176 Fakulteta za matematiko in fiziko 0 0 0
