20.500.12556/DKUM-71927 Vizualizacija naravne konvekcije diplomsko delo Visualization of natural convection Diplomska naloga se posveča problemu kako vizualizirati naravno konvekcijo. V ta namen smo izdelali 4 različne celice, ki nam bi to omogočale. S hkratnim gretjem celice od spodaj in hlajenjem od zgoraj smo v omejenem prostoru ustvarili pogoje za naravno konvekcijo. Pri eksperimentu smo z uporabo metode particle image velocimetry dobili hitrostna tokovna polja v celici. Tako smo lahko primerjali, kdaj je tok največji ter kam je usmerjeno in kakšno je hitrostno tokovno polje pri različnih pogojih in različnih celicah. Prišli smo do sklepov, da so hitrostna tokovna polja zelo urejena ter da z večjo temperaturno razliko intenzivnost narašča. Diploma thesis is focused on the problem how to visualize the natural convection. To make an experiment we created 4 different cells, which would make that possible. By simultaneously heating the cells from the bottom and cooling them at the top, we created conditions for natural convection in the closed area. During the experiment, we used the method known as particle image velocimetry to show the flow field. This enabled us to compare the velocity profile, direction of flow and to discovered how the velocity flow field looked like in different cells under different conditions. We have come to the conclusions that velocity flow fields are properly observed and that the rise in temperature difference increases the intensity of the flow. celice naravna konvekcija hitrostna tokovna polja cell natural convection velocity flow field true true false [A.
