Abstract

V diplomski nalogi je bil obravnavan križnotočni štiristopenjski rekuperativni prenosnik toplote z razširjenimi površinami. Medija v prenosniku sta voda ter dimni plini. Z analitičnim preračunom sem izračunala izstopne temperaturi vode in dimnih plinov ter učinkovitost obravnavnega toplotnega prenosnika. V nadaljevanju sem naredila simulacijo prenosnika in tako preverila ustreznost matematičnih enačb analitičnega preračuna. Naloga je bila izvedena s konstrukcijskim programom Creo Parametric 5.0.0.0 in programom za računsko dinamiko tekočin ANSYS CFX.

Secondary title:	Heat transfer in regenerative tube heat exchanger
Secondary abstract:	In my diploma, I looked at a regenerative heat exchanger with finned tubes. The heat exchanger has four passes and is crossflowed. The fluids used, are water end flue gases. I have used an analytic approach to calculate the exit temperatures of water and flue gases. I have also determined the efficiency of the heat exchanger. In order to verify the analytical results, I made a simulation in ANSYS CFX computational fluid dynamics. The geometry that is used in the simulation was constructed in Creo Parametric 5.0.0.0.
