Abstract
U ovom diplomskom radu, provedena je termodinamička analiza cijevnog lamelnog izmjenjivača topline. Cijevni lamelni izmjenjivač topline izveden je iz osnovnih tipova izmjenjivača topline. U radu se vrši analiza dviju različitih geometrija cijevnog lamelnog izmjenjivača topline s istim ulaznim parametrima. S vanjske strane cijevi, izmeĎu lamela, struji zrak zadane ulazne temperature i brzine. Kroz cijevi prolazi voda, te se zanemaruje otpor izmjeni topline na strani vode, a temperatura dodirne plohe cijevi i lamele, te cijevi i zraka uzima se konstantnom i jednakom temperaturi vode. Problem se definira kao stacionarni, trodimenzijski konvekcijsko – difuzijski. Korišteni računalni programi jesu Creo Parametric i Ansys Fluent. Diplomski rad u prvom dijelu bazira se na osnovnim oblicima izmjene topline, tipovima izmjenjivača topline, domeni te opisom primijenjene numeričke metode. Drugi dio rada bavi se dobivenim rezultatima i njihovom usporedbom i analizom. Kroz rad prikazana su i analizirana polja temperatura, vektori brzina, polja tlakova, izmijenjeni toplinski tokovi i koeficijenti prijelaza topline.
Abstract (english)
This graduate thesis is consisted of the thermodynamic analysis for the fine and tube heat exchanger. Fine and tube heat exchanger is made from basic type heat exchangers. The analysis is made for two different geometry of fine and tube heat exchanger with the same input parameters. Outside of tube, between fins, streams the air with input temperature and velocity. The water passes through the tubes and the resistance of heat transfer on the water side is ignored. The temperature of tube and fin’s touching surface, as well as tube and air’s touching surface is set as the constant and equal to the temperature of water. The case was defined as a stationary, three-dimensional convection-diffusion. The computer programs that were used are Creo Parametric and Ansys Fluent. The first part of graduate thesis is based on basic forms of heat change, types of heat exchanger, domain and description of applied numerical method. The other part of graduate thesis is based on results and their comparison and analysis. The temperature fields, vectors of velocity, pressure fields, total heat transfers and convection heat transfer coefficients are shown and analysed through the graduate thesis.
