Title: VPLIV GEOMETRIJE KANALOV NA IZBOLJŠANJE PRENOSA TOPLOTE Ploj, Dejan (Author)Škerget, Leopold (Mentor) More about this mentor... Ravnik, Jure (Co-mentor) UNI_Ploj_Dejan_2012.pdf (5,45 MB) Slovenian Undergraduate thesis (m5) 2.11 - Undergraduate Thesis FS - Faculty of Mechanical Engineering V diplomskem delu je obravnavan laminarni tok hladilne tekočine skozi kanale toplotnega prenosnika. S pomočjo računalniške dinamike tekočin sta izvedeni analiza in medsebojna primerjava tokovnih in toplotnih razmer različnih geometrij kanalov. Izvedena je tudi optimizacija, tako da je z obliko doseženo mešanje tekočine oziroma tanjšanje mejne plasti in s tem izboljšanje prenosa toplote. Problem je najprej obravnavan časovno neodvisno v dveh dimenzijah, nato časovno odvisno in na koncu še prostorsko. Na podlagi rezultatov numeričnih simulacij je bilo podanih nekaj predlogov za izdelavo in laboratorijsko preskušanje določenih izvedb toplotnih prenosnikov. Podane so tudi smernice za nadaljnje numerične analize. laminarni notranji tok, mejna plast, toplotni prenosnik, računalniška dinamika tekočin, Ansys 2012 [D.

Language: English INFLUENCE OF CHANNEL GEOMETRY ON THE ENHANCEMENT OF HEAT TRANSFER In this diploma work laminar flow of coolant through ducts of a heat exchanger is treated. Analysis and comparison of flow and heat conditions between different duct geometries are made using computational fluid dynamics. For the improvement of heat transfer an optimisation of duct geometries is given so that fluid mixing or thinning of boundary layer is achieved. At first the problem is considered as time independent two-dimensional, then as time dependent and at last as three-dimensional. Based on the results of numerical simulations a few suggestions for the development and testing of certain designs of heat exchangers have been provided. Guidelines for further numerical analysis are given. laminar internal flow, boundary layer, heat exchanger, computational fluid dynamics, Ansys
